I saw this bug on AMD64 Windows8.1 Refleaks 3.6: "test test_warnings failed -- multiple errors occurred; run in verbose mode for details" http://buildbot.python.org/all/builders/AMD64%20Windows8.1%20Refleaks%203.6/builds/38/steps/test/logs/stdio
The goal is to get a successful "./python -m test -R 3:3 -v test_warnings" run.

Oh cool, my bisect tool identified the bug!
haypo@selma$ ./python -m test.bisect -o bisect test_warnings test_warnings (...) Tests (1):
- test.test_warnings._WarningsTests.test_showwarnmsg_missing (...) Bisection completed in 14 iterations and 0:00:14
So the bug is that test_showwarnmsg_missing() removes the warnings._showwarnmsg attribute, but don't restore it.
https://github.com/python/cpython/pull/2504 fixes the issue.
