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:

====================================================================== ERROR: test_remove_signal_handler_error2 (test.test_asyncio.test_unix_events.SelectorEventLoopSignalTests)

Traceback (most recent call last): File "/home/skip/src/python/cpython/Lib/unittest/mock.py", line 1191, in patched return func(*args, **keywargs) File "/home/skip/src/python/cpython/Lib/test/test_asyncio/test_unix_events.py", line 219, in test_remove_signal_handler_error2 m_signal.valid_signals = signal.valid_signals AttributeError: module 'signal' has no attribute 'valid_signals'

Ran 1967 tests in 36.058s

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?
