We do this because clock() is not affected by timeBeginPeriod on Win32.

QueryPerformanceCounter is a little overkill for the amount of precision that

I consider acceptable. If someone submits a patch that replaces this code
|

with QueryPerformanceCounter, I wouldn't complain. Until then, timeGetTime

gets the results I'm after. -EMS
