What would be really neato would be to use the rtdsc (sp?) or equivalent
assembly instruction where available. Most processors provide such a thing and
it would give much lower overhead and much more accurate answers.
The main problem I see with this would be on multi-processor machines.
(QueryPerformanceCounter does work properly on multi-processor machines,
right?)
