I grouped all the processes on my system but a few into per-session
control groups by a quick python hack into CGFreak. It looks very
funny atleast, I never spawned so many groups before:

The big circle in the middle shows the cgroups alottment, the
satellites show the processes inside each cgroup. The number
on the perimeter is the SID.
