And just so you don't ask: There should not just be a Sleep(0) in the 
loop, but a sleep that gets shorter and shorter until a lower threshold 
is reached, where it skips to Sleep(0). That way we avoid hammering om 
WaitForMultipleObjects and QueryPerformanceCounter more than we need. 
And for all that to work better than just giving a timeout to 
WaitForMultipleObjects, we need the multimedia timer turned on.
