Ok, here is some code I wrote a while ago, and touched up a little
recently as someone else needed it.  As you may have noticed by the
line count, it is VERY wordy...hopefully some of it is useful.

This code returns a time value in units of 838 nanoseconds,
and I have found it quite useful.  Even though the examples I
provide are for fixed-frame-rate games, I have used this in
a crude ray-casting (yuk) demo I wrote a while back which will
run as fast as your CPU (or monitor/video) will allow. 

Lemme know if you create something cool with it!
