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
