To keep the list posted about this: we talked to the cgroup kernel guys about this and while it appears like the right thing to do this the kernel logic behind the option doesn't work correctly, and hence we shouldn't do this for now. And it appears likely that when the kernel fixes the behaviour it will be turned on by default anyway, without involving userspace. Stef, is that a big problem for you? Not sure what else we can do about this for now though...
