In Windows there is a possibility to set affinity.

See this tip :

You can choose the processors to use per program. On a quad-cpu system, you can
for example set POVRay on processor 1,2,3 and still have an entire processor for
your other programs.

I don't know if this will be implemented in the final POVRay 3.7 but duty cycle
was also useful.
