I'm thinking we need to lock you guys in a room and come back in 15 minutes.

Seriously, how are we to resolve this? We could lock me in a room and
cmoe back in 15 days, but there's no reason to believe that I'd emerge
with the best answer.

I tend to think that a cgroup-based controller is the way to go.
Anything else will need to be wired up to cgroups _anyway_, and that
might end up messy.
