Sorry for the second email. Where did you find the information on
granularity on sleep?
http://msdn.microsoft.com/en-us/library/windows/desktop/ms686298(v=vs.85).aspxstates
that a value of 0 will "[cause] the thread to relinquish the
remainder of its time slice to any other thread that is ready to run." I
cannot find information on implementation details.
