The behavior I see with Windows XP and Perl 5.14.2 is this: if a signal
handler is active, it's not called until the wait completes (because a
notification happens or it times out). I'm not clear whether you're
seeing the same thing.
I believe this is because of Perl's deferred signal handling:

I agree that's probably not the most desirable behavior, but I don't
know how to change it. I'd welcome a pull request
(https://github.com/madsen/win32-ipc) if you have a solution.
