[New-bugs-announce] [issue31479] Always reset the signal alarm on unit tests

New submission from STINNER Victor:
While fixing bpo-17085 on Python 2.7 (test_socket: cancel scheduled alarm on test failure), I noticed that not all unit tests currently always reset the signal alarm.
I propose to always use the pattern "try/finally: signal.alarm(0)" to make sure that a test doesn't "leak" a pending fatal signal alarm.
Attached PR fixes the issue.
I don't think that it's worth it to backport the fix, since it only impacts tests which fail, interrupted manually by CTRL+c or other corner cases.
