Garrett Wollman e2d4b1f051 Reduce jitter of Pentium microtime() implementation by letting the counter
free-run and doing a subtract in microtime() rather than resetting the
counter to zero at every clock tick.  In combination with the changes to
kern_clock.c, this should eliminate all the immediately obvious sources
of systematic jitter in timekeeping on Pentium machines.
