Because we'd like to have per-CPU run queues (for processor affinity
-- actually, I think the Mach "processor set" model is not a bad
example to follow here).
it just seems suboptimal to have to set a flag in every cpu_info when
there is a (random) process to run.
on a related issue, i kind of like the idea of real idle threads as
opposed to the method used for current SMP sysetms (where this is all
handled in MD code.)
