[issue39983] test.regrtest: test marked as failed (env changed), but no warning: test_multiprocessing_forkserver

[STINNER Victor]

STINNER Victor  added the comment:

"Warning -- Unraisable exception" is now logged, but the exceptions is not when 
sys.stderr is redirected. That's better than nothing, so I close the issue.

Moreover, test_multiprocessing_forkserver has been fixed.

Oh nice, my fix worked as expected: "Warning -- Unraisable exception" was 
logged! But the unraisable exception itself was not logged.

New submission from STINNER Victor :

Tests run with --fail-env-changed. test_multiprocessing_forkserver failed with 
"env changed", but no warning was logged to explain why :-(

PPC64LE RHEL7 3.8:
https://buildbot.python.org/all/#/builders/401/builds/69

./python  ./Tools/scripts/run_tests.py -j 1 -u all -W --slowest
