Thanks Davin.
I got onto a Windows 8 machine and confirmed the behaviour changed there, so
the version check in my patch is correct. Anyone opposed to the extra logic and
version check?

Tested Steve's code snippet on Windows 7 64-bit without the patch on default
(3.5) and got result: True
Not knowing the full history here, I blindly tried on the same Win7 system with
2.7.8 and got a False. Looks like Richard's patches made in #12328 were only
Steve Dower added the comment:
Attached a patch to 3.5 that resolves this, and I'll backport to 3.4. I haven't
got access to Windows 7 or 8 right now to test it, but it's fine on Vista
without the patch and 8.1 with the patch.
It'd be great if people could help check exactly which version of
David Bolen added the comment:
I've just brought a Windows 8 buildbot online (bolen-windows8) and can confirm
that this test does fail in the 3.4 and 3.x branches, and that it does so
consistently even if I execute the steps interactively.

What's the process for volunteering a buildbot? Email python-dev? I
*might* volunteer to set one up...

R. David Murray added the comment:
What information there is is here: http://wiki.python.org/moin/BuildBot.
Antoine Pitrou is the current buildbot master and will issue you a password
once you are set up, if you decide to do this. You can also talk to us on the
#python-dev irc channel.
R. David Murray added the comment:
All the buildbots are volunteer hosted and run, so we need someone to volunteer
to run a Windows 8 buildbot. That said, I'm not sure if we are formally
supporting Windows 8 yet or not. Actually, given the lack of a buildbot, I
suppose the answer is not :)
New submission from Walter Prins:
It appears that Windows 8 (Version 6.2.9200 x64) has introduced changes in
behaviour that causes the multiprocessing module's use of overlapped
PipeConnection to fail (Python 3.4 32bit and release 3.3.2 32bit).
This issue previously existed (see issue #12328

Does that test always fail?

Yes it does. I should've probably added in the original report that the
following test (test_strings) also fail,
