Log:
Argh, what was I thinking?? Don't (yet) halt the CPU in the idle loop
while waiting for an interrupt (rather than spinning on the runqueue status
bits), since the other cpu can put stuff in there and the sleeping cpu may
not get an interrupt for a while. When we have a reschedule IPI, this can
come back.
