Take the most extreme example:
while (hit_global_sgx_limit()) reclaim_from_this(cgroup);
You eventually end up with all of 'cgroup's pages gone and handed out to other users on the system who stole them all. Other users might cause you to go over the global limit. *They* should be paying part of the cost, not just you and your cgroup.
