Don't know about Windows and Mac but on Linux the CPUs are listed in /dev/cpu.  
With an X2 amd64 "$ ls /dev/cpu" return the directories "0    1".  So take 
the highest number and add one.  This might also be true for hyperthreaded 
machines such as P4s.

Finding the number of CPUs on the machine is a good idea but I think the user 
should be able to specify the number of processors that they want to use up 
to the number available in the machine since they might want to leave 
resources free for other tasks.
