[issue30703] test_multiprocessing_forkserver hangs on the master branch

[Antoine Pitrou]

Antoine Pitrou added the comment:

Using pthread_mutex_trylock() *and* disabling the CHECK_STATUS_PTHREAD() calls (which use the non-async-signal-safe fprintf()) at least seems to suppress the hangs on Matt's OS X machine (after more than 1000 runs).
