[issue20564] test_threadsignals.py "failed" on OpenBSD because too slow (> 3sec)

[STINNER Victor]

STINNER Victor added the comment:

To make test_lock_acquire_interruption and test_rlock_acquire_interruption more reliable, the test should maybe run a fresh Python process to get a well known number of threads. Some Python modules create C threads like Tkinter. faulthandler creates also an hiding C thread, but it is supposed to ignore all signals (it calls pthread_sigmask).

@Remi: Can you please test interrupt_lock_acquire.py? It should be the same than the unit test, but in a fresh Python process.
