DH		 52004-03-29 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
6
7 Introduce scm_debug_mode_p as a replacement for scm_debug_mode and
8 SCM_DEBUGGINGP:
9
10 * debug.h (scm_debug_mode_p, scm_debug_mode, SCM_DEBUGGINGP),
11 eval.c (scm_debug_mode_p): Deprecated scm_debug_mode and
12 SCM_DEBUGGINGP. Provided scm_debug_mode_p instead, to have one
13 single interface that also matches the naming conventions.
14 Probably scm_debug_mode_p should be part of the private interface
15 anyway.
16
17 * debug.h (scm_debug_mode_p), backtrace.c (display_error_body),
18 eval.c (SCM_APPLY, scm_trampoline_0, scm_trampoline_1,
19 scm_trampoline_2): Change uses of scm_debug_mode or SCM_DEBUGGINGP
20 to scm_debug_mode_p.
21
22
23 Deprecate direct access to scm_ceval, scm_deval and scm_ceval_ptr:
24
25 * eval.h (scm_ceval, scm_deval, scm_ceval_ptr), debug.h
26 (scm_ceval_ptr): Deprecated. Moved declaration of scm_ceval_ptr
27 from debug.h to eval.h.
28
29 * debug.h (SCM_RESET_DEBUG_MODE): Don't access scm_ceval_ptr any
30 more, just leave it with setting scm_debug_mode_p, which is
31 equivalent for practical purposes.
32
33 * deprecated.h (SCM_XEVAL, SCM_XEVALCAR): Call scm_i_eval_x
34 instead of *scm_ceval_ptr. Leave all evaluating to scm_i_eval_x.
35
36 * gdbint.c (gdb_eval): Call scm_i_eval_x instead of scm_ceval.
37
38 * eval.c (ceval, deval, scm_ceval, scm_deval): Made scm_ceval
39 static and renamed it to ceval throughout. Provide a new exported
40 but deprecated function scm_ceval as a wrapper for backwards
41 compatibility. The same is done for the deval/scm_deval pair of
42 functions.
43
44 * eval.c (CEVAL, SCM_CEVAL): Renamed SCM_CEVAL to CEVAL
45 throughout. Defined CEVAL to ceval or deval, based on compilation
46 phase.
47
48 * eval.c (SCM_XEVAL, SCM_XEVALCAR): Dispatch on scm_debug_mode_p
49 to ceval and deval instead of calling *scm_ceval_ptr.
50
51 * eval.c (dispatching_eval): New deprecated static function.
52
53 * eval.c (scm_ceval_ptr): Initialized to dispatching_eval in order
54 to emulate its old behaviour as closely as possible.
55
56
57 Change the evaluator such that only expressions for which pair? is
58 true are passed to CEVAL, and such that all other expressions are
59 evaluated outside of CEVAL:
60
61 * eval.c (EVAL): New, provided in analogy to EVALCAR. Evaluate an
62 expression that is assumed to be memoized already. All but
63 expressions of the form '(<form> <form> ...)' are evaluated inline
64 without calling an evaluator.
65
66 * eval.c (SCM_XEVAL, SCM_XEVALCAR, EVALCAR): Evaluate all but
67 expressions of the form '(<form> <form> ...)' inline without
68 calling an evaluator.
69
70 * eval.c (scm_i_eval_x, scm_i_eval, scm_ceval, scm_deval): Handle
71 the special case of unmemoized symbols passed on the top level.
72
73 * eval.c (CEVAL): Change calls to CEVAL to EVAL, except where it
74 is known that the expression passed to CEVAL is of the form
75 '(<form> <form> ...)'. Remove handling of the tc7-objects, since
76 now it is known that the input expression of CEVAL is a pair.
77
782004-03-29 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
5fb64383
DH		 79
80 * eval.c (is_self_quoting_p): New static function.

83
84 (copy_tree): Corrected typo in comment.

89
90 * list.c (s_scm_filter): remove "pointer" from doc string.
91
702551e6
HWN		 92 * gc.h (SCM_GC_CELL_TYPE): SCM_GC_CELL_TYPE uses SCM_GC_CELL_OBJECT.
93
94 * goops.h (SCM_NUMBER_OF_SLOTS): don't SCM_UNPACK the result.
95
96 * backtrace.c ("display_backtrace_body"): SCM_PACK before SCM_EQ_P
97 (display_frame): idem.
98 (display_backtrace_file_and_line): idem.
99
100 * tags.h (SCM_UNPACK): stricter typechecking on SCM_UNPACK
101 arguments.

KR		 105 * filesys.c (scm_getcwd, scm_readlink): Avoid memory leak on errors.
106
3cd23214
KR		 107 * numbers.c (scm_modulo): For inum/big and big/big, remove test of
108 big==0 since that never occurs.
109
110 * numbers.c, numbers.h (scm_modulo_expt): Renamed from
111 scm_modular_expt, matching scheme level name `modulo-expt'.
112
113 * numbers.c (scm_modular_expt): Return a negative remainder for a
114 negative divisor, the same as `modulo' does.
115
1162004-03-26 Eric Hanchrow <offby1@blarg.net>
117
118 * numbers.c, numbers.h (scm_modular_expt): New function.

123 return inexact as required by r5rs.
124
62360b89
DH		 1252004-03-24 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
126
127 * eval.c: Separated some definitions relevant for execution from
128 the memoization part of the file.
129
130 (copy_tree): New static function
131
132 (scm_copy_tree): Rewritten to fix two kinds or bugs: First, cyclic
133 structures are detected now and will lead to an exception instead
134 of forcing guile to run in an endless loop, using up all the
135 system's memory. Second, arrays in the cdr of an improper list
136 are now copied. See the new test cases in eval.test.
137
1382004-03-24 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
b28f5b3c
DH		 139
140 * posix.c (scm_gethostname): Make sure len is initialised before
141 it is used. Restructured to (hopefully) represent possible
142 configurations more clearly in the code. Added unwind handler.
143
3bd3bae8
KR		 1442004-03-23 Kevin Ryde <user42@zip.com.au>

254bf78d
MV		 1492004-03-21 Marius Vollmer <mvo@zagadka.de>
150
151 * read.c (skip_scsh_block_comment): Also recognize '\r' as a line
152 terminator. Rewritten the logic as a state machine, I must have
153 been doing too much VHDL lately...
154
155 * eval.c (scm_ceval, scm_deval): Explicitely evaluate ports to
156 themselves. Thanks to Han-Wen Nienhuys!
157
158 * list.c: Changed docstrings so that they no longer talk about
159 returning 'pointers' to something.
160
009c34a2
HWN		 1612004-03-20 Han-Wen Nienhuys <hanwen@xs4all.nl>
162
163 * gc.c: remove set_debug_cell_accesses! when
164 SCM_DEBUG_CELL_ACCESSES is not defined. Scheme source code should
165 use (if (defined? 'set-debug-cell-accesses!) .. ) to switch on
166 debugging conditionally.
167
54733c95
KR		 1682004-03-21 Kevin Ryde <user42@zip.com.au>

197
198 * numbers.c (guile_ieee_init): Use C99 INFINITY and NAN when
199 available. Test HAVE_DINFINITY and HAVE_DQNAN for those globals, in
200 particular don't assume "defined (__alpha__) && ! defined (linux)"
201 means OSF. Remove "SCO" code, which was not really SCO specific and
202 which John W. Eaton advises should be long past being needed.
203
204 * posix.c (scm_execl, scm_execlp, scm_execle): Avoid memory leak under
205 error throw.
206
72ea45ac

KR		 2432004-02-18 Kevin Ryde <user42@zip.com.au>
244
245 * num2integral.i.c (INTEGRAL2BIG): WORDS_BIGENDIAN not right for word
246 order parameter to mpz_import, in fact with just one word there's no
247 order to worry about at all.
248
249 * numbers.c (scm_num_eq_p): For real==frac, complex==frac, frac==real
250 and frac==complex, make an exact comparison rather than converting
251 with fraction2double.
252
253 * posix.c, putenv.c, stime.c (environ): Use _NSGetEnviron in Darwin
254 shared library, since environ is not directly available there.
255
256 * script.c (scm_shell_usage): Print to stdout for --help, per GNU
257 standard.
258
259 * stime.c (scm_localtime, scm_gmtime, scm_mktime): Provide a default
260 errno EINVAL in case localtime and gmtime don't set it.
261 (scm_mktime, scm_strptime): Forcibly use errno EINVAL for our
262 SCM_SYSERROR, since mktime and strptime generally don't set errno.

278 code in order to avoid compiler used uninitialized warnings.
279
280 * hashtab.c, hashtab.h (scm_hash_map_to_list): Renamed from
281 scm_hash_map.
282 (scm_hash_fold): Use scm_call_3 directly in the call to
283 scm_internal_hash_fold instead of going via fold_proc (which is
284 now removed).
285 (scm_hash_for_each): Use a trampoline +
286 scm_internal_hash_for_each_handle.
287 (scm_internal_hash_for_each_handle, scm_hash_for_each_handle): New
288 functions.

293 (scm_set_port_line_x): In docstring, note first line is 0.
294 (scm_port_column): In docstring, there's no default to current input
295 port, and remove shared port-line @defun.
296 (scm_set_port_column_x): In docstring, there's no default to current
297 input port, note first column is 0, remove shared set-port-line!
298 @defun.
299
3da7f6b2
KR		 300 * ramap.c (scm_array_fill_x): For fvect and dvect, use scm_num2dbl to
301 convert args the same way that array-set! does.
302
303 * unif.c (scm_make_uve, scm_array_p): Allow fraction 1/3 as prototype
304 for dvect.
305 (scm_array_p): Add missing "break"s in switch, fix llvect test look
306 for "l" not "s", fix dvect to be false for singp(prot) since such a
307 value is for fvect.
308 (scm_array_prototype): Return 1/3 for dvect, rather than 0.33..33.
88531a74
KR		 309 (exactly_one_third): New variable.

320 `escaped-parens'.
321 (s_vector): New.
322 (scm_lreadr): Use scm_lreadparen1 instead of scm_lreadparen. Make
323 handling of elisp vector syntax dependent on SCM_ENABLE_ELISP and
324 `elisp-vectors' option instead of SCM_ELISP_READ_EXTENSIONS.
325 Allow "\(" and "\)" in strings when SCM_ENABLE_ELISP defined and
326 `escaped-parens' option set.
327 (scm_read_token): If elisp vector syntax active, disallow [ and ]
328 in tokens.
329 (scm_lreadparen): Rewrite as interface to scm_lreadparen1.

343 overwriting FORMS) also when a letrec is constructed, not only
344 when no definitions are found. Do not return rewritten expression
345 to emphasize the in-place rewriting. Changed all users.

96e3b2f8
MV		 377
378 * fluids.c (scm_c_with_fluids): Use frames instead of adding to

fc6bb283
MV		 387
388 * dynwind.c (scm_frame_end): Do not use scm_i_dowinds. Instead,
389 do the unwinding directly. It is simple enough.

521 * eval.c (s_bad_define): New static identifier.
522
523 (m_body): Fixed comment.
524
525 (scm_m_define): Don't generate memoized code for definitions that
526 are not on the top level. As a consequence, no memoized code at
527 all is generated for definitions any more: Top level definitions
528 are executed immediately during memoization and internal
529 definitions are handled separately in m_expand_body.
530
531 (scm_unmemocopy, unmemocopy): Removed code for unmemoizing
532 definitions. Consequently, there is no unmemoizing code any more
533 that might modify the environment. Thus, the old scm_unmemocopy
534 is removed and the old unmemocopy is renamed to scm_unmemocopy.
535
536 (SCM_CEVAL): The SCM_IM_DEFINE keyword can no longer occur in
537 memoized code. Call EVALCAR for continuations. Prefer !SCM_NULLP
538 over SCM_NIMP in places, where the argument is known to be part of
539 a proper list.

547 to share some shifting.
548
549 * numbers.c (scm_integer_expt): Don't mpz_init after scm_i_clonebig or
550 scm_i_mkbig, since they do so already. Don't mpz_clear a bignum SCM,
551 since gc does this.

562
563 * numbers.c (scm_i_fraction_equalp): Do not treat the return value
564 of scm_equal_p as a C boolean, use SCM_FALSEP. Previously, all
565 fractions were equal to each other regardless of value. Ooops.

1043 This set of patches eliminates the dependency between the
1044 implementation of evaluator specific memoization codes and special
1045 constants like #f, '() etc. ('flags'), which are not evaluator
1046 specific. The goal is to remove definitions of evaluator
1047 memoization codes completely from the public interface. This will
1048 make it possible to experiment more freely with optimizations of
1049 guile's internal representation of memoized code.
1050
1051 * objects.c (scm_class_of): Eliminate dependency on SCM_ISYMNUM.

1057 memoization codes.

1085 The typecode of the former 14th short instruction is now used to
1086 represent long instructions. Changed some comments to reflect
1087 this fact.

1098 code that is separate from all instructions, one level of dispatch

1131 0.0==some_expression to some_expression==0.0. The latter is
1132 better readable. The former is preferred by some people, since it
1133 leads to a compiler error when confusing == with =. However, when
1134 using gcc, a warning will be issued if in an if-statement an
1135 assigment appears. Since many Guile developers are using gcc,
1136 such errors will not remain unnoticed anyway. We can therefore
1137 focus on better readability.

1447 This set of patches separates the representation of the cxr family
1448 of functions (car, cdr etc.) from the dsubr family of functions

1670 or from user provided primitive memoizing macros. The reason is,
1671 that the internal memoizers are the only ones that are allowed to
1672 transform their scheme input into memoizer byte code, while all
1673 other memoizing macros may only transform scheme code into new
1674 scheme code.
1675
1676 To achieve this, a new macro type 'builtin-macro!' is introduced.
1677 Currently, 'builtin-macro!'s are handled as memoizing macros, but
1678 this will change when the memoizer and executor are separated.

1690 builtin-macros are handled equally to memoizing macros.

1779 This set of patches contains no functional changes, only debatable
1780 minor stylistic ones. Still, in order to prepare a patch between
1781 my local copy and the CVS version, I decided to submit the changes

1825 an array of SCM values instead of an array of characters. Avoid
1826 bytewise copying of SCM elements. Avoid allocating memory on the
1827 stack with alloca. Fixed some comments.

2510 * Makefile.am: scmconfig.h is now generated by building and
2511 running gen-scmconfig.h and capturing its output. gen-scmconfig
2512 uses config.h and the configure.in generated gen-scmconfig.h to
2513 decide what to output. See gen-scmconfig.c for details.
2514 (noinst_PROGRAMS): add gen-scmconfig.
2515 (gen_scmconfig_SOURCES): new variable.
2516 (gen-scmconfig.$(OBJEXT)): new target - be careful to handle
2517 cross-compiling right.
2518 (scmconfig.h): build scmconfig.h from gen-scmconfig's output.

MD		 2586 This fixes a serious GC bug, introduced during the latest
2587 reorganization of the GC, which disabled freeing of structs and

2604 * modules.c (scm_modules_prehistory): Changed from 2001 to 1533
2605 (current number of prehistory bindings; hashtable code will select
2606 a prime which is greater than this value).

2620
2621 The following changes introduce the use of resizable hash tables
2622 throughout Guile. It also renames the old *-hash-table* functions
2623 to *-alist-vector* and places them, together with the rest of the
2624 weak vector support, in the module (ice-9 weak-vector). We should
2625 probably introduce a new, better, API for weak references, for
2626 example "weak pairs" a la MIT-Scheme. (In Chez scheme, they even
2627 look like and are used like ordinary pairs.)
2628
2629 * environments.c (obarray_enter, obarray_retrieve, obarray_remove,
2630 leaf_environment_fold, obarray_remove_all): Use hashtable

2811 This change makes it possible for one thread to do lazy sweeping
2812 while other threads are running. Now only the mark phase need to
2813 have all threads asleep. We should look further into this issue.
2814 Presently, I've put the locking of scm_i_sweep_mutex at
2815 "conservative" places due to my current lack of knowledge about
2816 the garbage collector. Please feel free to restrict these regions
2817 further to allow for maximal parallelism!
2818
2819 * gc.c, gc.h (scm_i_sweep_mutex): New mutex.
2820
2821 * gc.c (scm_gc_for_newcell), gc-malloc.c (scm_realloc,
2822 scm_gc_register_collectable_memory): Substitute locking of
2823 scm_i_sweep_mutex for calls to scm_i_thread_put_to_sleep.
2824 (scm_igc): Lock sweep mutex here instead of in callers; Calls to
2825 scm_i_thread_put_to_sleep/scm_i_thread_wake_up used to demarkate
2826 the single-thread section (which now only contains the mark
2827 phase).
2828 (scm_gc): Don't lock sweeo mutex here since scm_igc locks it;
2829 Removed SCM_DEFER/ALLOW_INTS. Simply call scm_igc directly.

2941 * threads.c (create_thread): Remember root object until the handle
2942 of the new thread is on all_threads list.
2943
2944 * root.c (scm_make_root): Moved copying of fluids until after
2945 creation of root handle so that the fluids are GC protected. Also
2946 removed the critical section.

2987 These changes remove scm_ints_disabled (which hasn't has any
2988 effect in Guile for quite some time).
2989

MD		 3007 These changes are the start of support for preemptive
3008 multithreading. Marius and I have agreed that I commit this code
3009 into the repository although it isn't thoroughly tested and surely
3010 introduces many bugs. The bugs should only be exposed when using
3011 threads, though. Signalling and error handling for threads is
3012 very likely broken. Work on making the implementation cleaner and
3013 more efficient is needed.
3014
3015 * __scm.h (SCM_ALLOW_INTS_ONLY): Removed.
3016 (SCM_NONREC_CRITICAL_SECTION_START,
3017 SCM_NONREC_CRITICAL_SECTION_END, SCM_REC_CRITICAL_SECTION_START,
3018 SCM_REC_CRITICAL_SECTION_END): New macros.
3019 (SCM_CRITICAL_SECTION_START/END): Defined here.

3021 * eval.c: Insert SOURCE_SECTION_START / SOURCE_SECTION_END around
3022 the three calls to scm_m_expand_body.

3025 (SCM_FREELIST_CREATE, SCM_FREELIST_LOC): New macros.

3028 scm_t_key;
3029
3030 * gc.c, gc-freelist.c, inline.h: Use SCM_FREELIST_LOC for freelist
3031 access.
3032
3033 * gc-freelist.c (scm_gc_init_freelist): Create freelist keys.
3034
3035 * gc-freelist.c, threads.c (really_launch): Use
3036 SCM_FREELIST_CREATE.
3037
3038 * gc-malloc.c (scm_realloc, scm_gc_register_collectable_memory):
3039
3040 * gc.c (scm_i_expensive_validation_check, scm_gc,
3041 scm_gc_for_newcell): Put threads to sleep before doing GC-related
3042 heap administration so that those pieces of code are executed
3043 single-threaded. We might consider rewriting these code sections
3044 in terms of a "call_gc_code_singly_threaded" construct instead of
3045 calling the pair of scm_i_thread_put_to_sleep () and
3046 scm_i_thread_wake_up (). Also, we would want to have as many of
3047 these sections eleminated.
3048
3049 * init.c (scm_init_guile_1): Call scm_threads_prehistory.
3050
3051 * inline.h: #include "libguile/threads.h"

3053 * pthread-threads.h: Macros now conform more closely to the
3054 pthreads interface. Some of them now take a second argument.
3055

3067 (SCM_MICRO_VERSION): use @--@ substitution now.
3068 (scm_effective_version): new function prototype.

3071 effective-version.
3072
3073 * Makefile.am (schemelibdir): VERSION -> GUILE_EFFECTIVE_VERSION.
3074 (libpath.h): use GUILE_EFFECTIVE_VERSION to compute
3075 SCM_LIBRARY_DIR.
3076 (version.h): generate this here rather than configure.in. This
3077 approach tracks source edits better (i.e. more immediately).
3078 Might be worth considering for other .in files too.

3082 Reorganized thread package selection. A thread package now only
3083 implements a small set of pthread like functions and Guile
3084 implements the rest on top of that. Guile's implementation is
3085 what the "coop-pthreads" package has been previously. Support for
3086 "coop" threads has been removed until I get time to add it again.
3087
3088 * Makefile.am (libguile_la_SOURCES): Removed iselect.c.
3089 (noinst_HEADERS): Removed coop-threads.c, coop-threads.h, coop.c,
3090 null-threads.c, coop-pthreads.c.
3091 (modinclude_HEADERS): Removed coop-defs.h, coop-pthreads.h. Added
3092 pthread-threads.h.
3093
3094 * validate.h (SCM_VALIDATE_THREAD): Moved to threads.h.
3095
3096 * threads.h: Do not include "libguile/coop-defs.h". Include
3097 "libguile/pthread-threads.h" for USE_COPT_THREADS. Removed
3098 (previously deprecated) C level thread API prototypes. They are
3099 now in the thread package specific headers, "null-threads.h" and
3100 "pthread-threads.h".
3101 (SCM_VALIDATE_THREAD, SCM_VALIDATE_MUTEX, SCM_VALIDATE_CONDVAR):
3102 New.
3103 (scm_threads_init): Removed.
3104 (SCM_CRITICAL_SECTION_START, SCM_CRITICAL_SECTION_END,
3105 SCM_THREAD_SWITCHING_CODE, scm_i_switch_counter,
3106 SCM_I_THREAD_SWITCH_COUNT): Define here.
3107 (scm_single_thread_p): Removed.
3108 (scm_call_with_new_thread): Take two args directly instead of list
3109 of two args.
3110 (scm_i_thread_data, scm_i_set_thread_data, SCM_THREAD_LOCAL_DATA,
3111 SCM_SET_THREAD_LOCAL_DATA): Define here.
3112
3113 * threads.c: Merged with "coop-pthreads.c".
3114
3115 * null-threads.h: Implement pthread-like API as a set of macros.
3116
3117 * pthread-threads.h: New, implement pthread-like API by deferring
3118 to pthread itself.
3119
3120 * init.c (scm_init_guile_1): Do not call scm_init_iselect, which
3121 has been lost in the reorganization.

3125 The following change makes it possible to move procedure
3126 application dispatch outside inner loops. The motivation was
3127 clean implementation of efficient replacements of R5RS primitives
3128 in SRFI-1.
3129
3130 The semantics is clear: scm_trampoline_N returns an optimized
3131 version of scm_call_N (or NULL if the procedure isn't applicable
3132 on N args).
3133
3134 Applying the optimization to map and for-each increases efficiency
3135 noticeably. For example, (map abs ls) is 8 times faster than
3136 before.
3137
3138 * eval.h (scm_t_trampoline_1, scm_t_trampoline_2): New types.
3139
3140 * eval.c, eval.h (scm_trampoline_1, scm_trampoline_2): New functions.
3141
3142 * eval.c (call_subr2_2, call_lsubr_2, call_closure_2): New functions;
3143 (map, for-each): Handle also application on two args as a special
3144 case; Use trampolines.
3145
3146 Other changes:
3147
3148 * sort.c (scm_cmp_function): Choose subr2less for scm_tc7_subr_2o;
3149 (subr2oless): Removed.
3150 (scm_restricted_vector_sort_x): Use scm_return_first to keep the
3151 vector GC protected.
3152
3153 * eval.c (check_map_args): Use scm_out_of_range_pos instead of
3154 scm_out_of_range.

3263 scheme for triggering signal handlers, to simplify take_signal.
3264 (take_signal): Simplified, to avoid race conditions.
3265 (scm_sigaction_for_thread): Use new Scheme. Validate that thread
3266 hasn't exited yet.
3267
3268 * async.c (scm_async_click): Reset pending_asyncs, handle
3269 signal_asyncs. Don't set cdr of a non-signal async to #f.
3270 (scm_i_queue_async_cell): Do not check cdr of cell for #f, queue
3271 always. Set pending_asyncs.
3272 (scm_system_async_mark_for_thread): Check that thread has not
3273 exited.
3274 (scm_unmask_signals, decrease_block): Call scm_async_click after

3292 USE_COPT_THREADS to not protect the slot initializers.
3293
3294 * init.c (scm_init_guile_1): Call scm_init_thread_procs. This is
3295 because threads need to be initialized before the stack, but
3296 gsubrs such as scm_timed_condition_variable_wait can only be
3297 created later.
3298
3299 * threads.h: Include "coop-pthreads.h" when requested.
3300 (scm_threads_make_mutex, scm_threads_lock_mutex,

3317 (scm_try_mutex, scm_broadcast_condition_variable): Newly
3318 registered procedures.
3319 (scm_wait_condition_variable, scm_timed_wait_condition_variable):
3320 Use the latter as the procedure for "wait-condition-variable",
3321 thus offering a optional timeout parameter to Scheme.
3322 (scm_wait_condition_variable): Implement in terms of
3323 scm_timed_wait_condition_variable.
3324 (scm_mutex_init, scm_mutex_lock, scm_mutex_trylock,
