Sorry, I forgot to mention:
- if you can't remove the cgroup because it's not empty,
- if the process remaining in the cgroup cannot be killed (for instance, 
because it's in "uninterruptible sleep" state),
- if you can't move the said process in a different cgroup (with e.g. 
"echo $PID > /cgroup/othercgroup/tasks"),
- ... then you can still rename the old cgroup.
