    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?
