    It's quite simple. If you use timeBeginPeriod() and Sleep() you give up the
    CPU while waiting. I think the same might be the case for
    CreateWaitableTimer(). On the other hand, if you're using
    QueryPerformanceCounter() what are you going to do while you wait for your
    timeout to expire ?

    I didn't say you WILL hog the CPU, I said you'll have to be real careful NOT
    to.
