test patch

So I was trying to come up with the patch that would show this behaviour.
As seen windows doesn't pump messages either, however it does PEEK at messages
so that they will not trigger MsgWaitForMultipleObjects again, if our
CoWaitForMultipleHandles would also do that then it will not be an issue as
CoWaitForMultipleHandles will not look at those messages in the queue again.

This change to test makes test fail on wine but it succeeds on windows.
