Details

:mstange suggested that we may want to replace ::Sleep(milliseconds) in the profiler Sampler loop with SetWaitableTimer, which has a better-that-millisecond precision.
But we should verify that it can in fact sleep for less than a millisecond.

This could potentially help with bug 1574815 (effective minimum sampling interval is 2ms on Windows).
