;; FIXME: The following exec tests are disabled since on an i386 debian with
;; glibc 2.3.2 they seem to interact badly with threads.test, the latter
;; dies with signal 32 (one of the SIGRTs).  Don't know how or why, or who's
;; at fault (though it seems to happen with or without the recent memory
;; leak fix in these error cases).
