Note that this happens ONLY if both threads of execution are processor
mobile.  If your system supports user-space threads as part of a 
process and the process can't be split across CPUs, you might as well
have a UP system.  (Except everything else can run on the other
processor, so SMP is still a small win.)

This is the situation with threads and SMP in -current.
