procs, not threads, can be "wired" to specific
processors.  so if your interest is to wire tasks (for lack of a
better term) to processors, you can do that with procs.

on modern pc hardware, the gulf between memory and
the processor is large enough, that i'm not sure that you'd
want to wire procs to processors.  wiring data to processors
would make more sense.
