Actually, you don't need any timeout at all.
WaitForSingleObject(INFINITE) keeps on running if the event object is
kept signaled, so performance is not an issue. We can use 'manual'
events to keep the Event object open all the time unless explicitly
turned off via a signal thread.
Implementation difficulties aside, what is more attractive from an
aesthetic standpoint? Releasing (and supporting) a 100 line binary
kernel driver for win32 or adding polling to the source in all the key
loops?
