Message132904
The problem is that faulthandler's thread (faulthandler_thread) receives the SIGALRM signal: the signal interrupts sem_timedwait() which returns EINTR. PyThread_acquire_lock_timed() retries sem_timedwait() and so the other thread executing sendall() is not interrupted.
The solution is to configure which signals are handled by faulthandler_thread() using pthread_sigmask():

I forced a build on x86 FreeBSD (custom) buildbot:

I already tested sigprocmask() on FreeBSD (in my VM) and it works as expected: test_socket doesn't block anymore. |
