I think the fundamental problem is the scheduler doesn't have a clue
about cpu affinity, and MacOSX is lacking any APIs or command line
interfaces that would allow the app or admin to give it a clue (like
you can on Linux, Solaris, etc).

CHUD contains such an api (utilBindThreadToCPU), but it's undocumented and therefore only suitable for experimenting.
