On the 3.7 branch, "make test" routinely fails to terminate. (Pretty
vanilla Ubuntu 17.10 running on a Dell Laptop. Nothing esoteric at all)
Lately, it's been one of the multiprocessing tests. After a long while
(~2000 seconds), I kill it, then it complains many times about lack of a
valid_signals attribute in the signal module:
======================================================================

Re-running test 'test_signal' in verbose mode
then reruns test_signal in verbose mode.
Earlier today, a run succeeded, so I'm guessing a race condition exists in
the test system. I recall encountering a similar problem a few weeks ago
and discovered this open ticket:
https://bugs.python.org/issue33099
Should I expect this as the normal behavior?
