[New-bugs-announce] [issue17384] test_logging failures on Windows

[Ezio Melotti]

New submission from Ezio Melotti:

test_logging is failing on some buildbots:
     test_logging::AMD64 Windows7 SP1 3.x a0b750 42970c 9aafc0
     test_logging::x86 Windows Server 2003 [SB] 3.x 9aafc0 6b69c1 c261b7
     test_logging::x86 XP-4 3.x 6b69c1 c261b7
     test_logging::x86 XP-5 3.x c261b7 7e8184

Only the Windows buildbots on 3.x seems to be affected.  The failing tests were introduced in #11557.

See e.g.:
http://buildbot.python.org/builders/x86%20XP-5%203.x/builds/1946/steps/test/logs/stdio
