It is a for controlling and distributing resources.  That part doesn't
change.  It's just not built to be used directly by individual
applications.  It's an admin tool just like sysctl - be that admin be
a human or userland base system.

There's a huge chasm between something which can be generally used by
normal applications and something which is restricted to admins and
base systems in terms of interface generality and stability, security,
how the abstractions fit together with the existing APIs and so on.
cgroup firmly belongs to the former.  It still serves the same purpose
but isn't, in a way, developed enough to be used directly by
individual applications and I'm not even sure we want or need to
develop it to such a level.

Thanks.
