I'm gonna commit these three patches.  I hope that the existing
in-process usages can move on to other mechanisms but recognize that
it's an actual use case and we may eventually decide to allow further
nesting cgroups at the leaf and allow separating threads of the same
process with only perf-task controllers.  I *strongly* hope it doesn't
come to that tho.

As __DEVEL__sane_behvior is currently the playground for testing new
stuff, I'm gonna commit these for now.  If it doesn't fan out, we can
add it back, but preferably under a new name "cgroup.tasks" and with
whole lot more restrictions.

Thanks.
