Question is: do you need to know the number of CPUs (why?) or do you need
to know the number of CPUs which you're currently allowed to use or do you
need to know the maximum number of CPUs which you are allowed to bind
yourself to, or what?

I can see responsible programs checking Ncpu before deciding how many threads to start, so it seems that some accurate info could be useful in the real world.
