I'm really not that at home with all that cgroup fiddling, so I'd like a
word from the two Pauls..

Questions I have at the moment:

- do we really need a new workqueue for this? Can't we use the regular
keventd stuff, now that Oleg fixed the get_online_cpus() thing?
(3da1c84c00c7e5fa8348336bd8c342f9128b0f14)

- aren't there funny races with the async_rebuild_sched_domains()
stuff?
