Can you try this fix?

(I can also just commit that and the test_unix_events.py fix for AIX and hope for the best.)

If you are asking to me: again, I don't own a Windows 2008 copy. Just commit and then watch buildbots :-)

New changeset 368b74823c76 by Guido van Rossum in branch 'default':
asyncio: Hopeful fix for issue 19765.
http://hg.python.org/cpython/rev/368b74823c76

I didn't see the failure recently, so I hope that it was fixed. I close the issue. I will reopen it if I see the failure again.

Thanks Guido for your fix.
