STINNER Victor added the comment:

I tried and failed to reproduce the bug manually on the FreeBSD 10 buildbot.

I ran 14 iterations of "./python -m test test_subprocess -v -F 
--fail-env-changed" and 50 iterations of "./python -m test test_subprocess -m  
test_leak_fast_process_del_killed -F".

STINNER Victor added the comment:

I made many changes in tests to prevent leaking zombie processes. Let's hope 
that it was enough to fix this bug. Since the bug occurred randomly, it's hard 
to say. I close the bug, but will reopen it if the bug occurs again.
