Oh, I'm probably mixing up two things.

1. When delegating, cgroup.threads should be delegated. Doing that
selectively doesn't achieve anything meaningful.

2. I haven't thought much about delegating a sub-protion of a threaded
subtree. Everything works the same way. I just can't think of a
use case.

Thanks.
