I'm using MegaPOV 0.4a under Windows 2000.  I just noticed that when doing
the photon mapping pass, the CPU utilization dropped steadilly from the
initial 100% down to as low as 9% before it finished.  The memory usage was
moderate, and also varied a great deal between 2 and 10 MB, so it wasn't
swapping.  HandleEx shows that there were no interesting files open, so
waiting on I/O would not account for it.

WHY would the system be idle so much when MegaPOV is running?  I would
expect it to use 100% CPU if nothing else needed attention.
