+/* In the old days, SCM_CRITICAL_SECTION_START stopped signal handlers

+ consistent state etc. And since the scheme code could do a stack
+ swapping new continuation etc, signals had to be deferred around
+ various C library functions which were not safe or not known to be
+ safe to swap away, which was a lot of stuff.
+
+ These days signals are implemented with asyncs and don't directly
+ run scheme code in the handler, but hold it until an SCM_TICK etc
+ where it will be safe. This means interrupt protection is not
+ needed and SCM_CRITICAL_SECTION_START / SCM_CRITICAL_SECTION_END is
+ something of an anachronism.
+
+ What past SCM_CRITICAL_SECTION_START usage also did though was
+ indicate code that was not reentrant, ie. could not be reentered by
+ signal handler code. The present definitions are a mutex lock,
+ affording that reentrancy protection against the new guile 1.8
+ free-running posix threads.
+
+ One big problem with the present defintions though is that code which
+ throws an error from within a DEFER/ALLOW region will leave the
+ defer_mutex locked and hence hang other threads that attempt to enter a
+ similar DEFER/ALLOW region.
