Same here.

I guess the Windows scheduler gives comparatively long time slices to 
processes, and doesn't cut them short even if higher-priority processes 
are ready. So while in /theory/ applications shouldn't bother about 
scheduling, in /practice/ it would be good if POV-Ray yielded its time 
slices now and again, at least on Windows systems.
