From cgroups' viewpoint, root is where it's at. The task isn't consumed
by autogroup either, it's only borrowed until cgroups claims it.

Would you prefer that when you mount /cgroups, you see a nearly empty
root task list because box was booted with autogroup enabled? Should
tasks appear and disappear on the fly while you're watching?

The goal is peaceful coexistence. The user can turn either or both both
on/off at his/her whim.
