    I'm glad to hear that! But the cpu resource controller has
    some problems, for example:

    - The controller only controls the time_slice value and doesn't
    care the balance of cpus (the controller leaves balancing to
    the existing balancing code in the scheduler). So far I don't
    have any good idea to solve this.

    - The controller holds a spinlock once per 1 second. I don't
    know this is permissive or not, but the current scheduler
    doesn't hold any spinlocks normally, so...

    KUROSAWA, Takahiro
