    I see but how is this different from userland just creating the leaf
    cgroup? I'm not sure what this actually enables in terms of what can
    be achieved with cgroup. I suppose we can argue that this is more
    convenient but I'd like to keep the interface orthogonal as much as
    reasonably possible.

    Thanks.
