This C routine is considered obsolete (as opposed to the shell command by
the same name). The interaction of this function with SIGALRM and other
timer functions such as sleep(), alarm(), setitimer(), and nanosleep() is
unspecified (CWE-676). Use nanosleep(2) or setitimer(2) instead.
usleep(100000); // give 'gdb --waitfor=' a chance to find this proc

Check buffer boundaries if used in a loop including recursive loops
(CWE-120, CWE-20).

data/libdispatch-0~svn197/testing/summarize.c:29:31: [1] (buffer) strlen:
Does not handle strings that are not \0-terminated; if given one it may
perform an over-read (it could cause a crash if unprotected) (CWE-126).
