Charles-François Natali <neolo...@free.fr> added the comment:
test_multiprocessing frequently hangs on FreeBSD < 8 buildbots, and this
probably has to do with the limit on the max number of POSIX semaphores:
"""

"""
There are probably dangling semaphores, since the test doesn't use that much
POSIX semaphores. Either way, we can't do much about it...
