Sure, lets start by getting their use-case, then see if cpuset is the
right solution and if so take it from there.

That said, the whole suspend/resume 'problem' does seem worth fixing and
is a very special case where we absolutely know we're going to get back
in the state we are in and userspace isn't actually running. So ideally
we'd go with the bhat's patch that skips the sched_domain rebuilds
entirely +- some bug-fixes ;-).
