There is. I beleive QueryPerformanceCounter has sub-mirosecond
resolution.

Can we just replace gettimeofday() with a version that's basically:
if (never_run_before)
GetSystemTime() and get current timer for baseline.
now = baseline + current timer - baseline timer;
return now;

Or do we need to make changes at the points where the function is
actually called?
