The bug is still alive:
https://buildbot.python.org/all/#/builders/168/builds/294

I found a bug using attached mp_debug.patch.

I wrote PR 10755 to try to fix it.

I have access to FreeBSD CURRENT buildbot. I only reproduced the bug once using:

./python -m test -v test_multiprocessing_fork -m WithThreadsTestPool --fail-env-changed -F 

I ran this command 4 times in parallel in 4 terminals, but I failed to reliably reproduce the bug. Even if I stress the computer using "./python -m test -j4 -r" run in different shell, or using my "system_load.py 3" script, I fail to trigger the bug.
