Ah I see what you're saying, the polling isn't the WaitForSingleObject,
it's that the main thread that's going to have to poll something to see
if the thread that's doing the WaitForSingleObject has woken up and set
a signal or something.
WaitForSingleObject itself isn't polling the same way select() isn't
polling..
Anyway, this article has an interesting twist on the issue:
http://www.codeproject.com/threads/queueuserapcex.asp
It uses a driver to set a thread into an alertable state, so that an APC
sent with QueueUserAPC() can be delivered any time. It's kinda messy
that it has to use a driver to get the job done but OTOH it gives you
signals that work pretty similarly to what you get with Unix I believe.
