Your cpu_idle routines need to obey the following rules:
The cpu_idle() routines you suggest return, which is "unexpected"

Eek! They shouldn't.
That would be a bug... but I don't see it (in i386)
i386's mwait_idle, default_idle, poll_idle, etc. of course will
return (when need_resched() goes high). Then cpu_idle() will then
call schedule()
Or did the list of rules erroneously imply that it should return?
Anyway, thanks for casting your eye over this, much appreciated.
