I myself really prefer this in the cpu controller.
Besides the bytes vs objects things, Whenever you create a process, at 
some point it will end up in the runqueues to be scheduled. It is a 
natural point of accounting.

Either that, or making it a core feature of cgroups, like limiting the 
number of processes in the tasks file (just have to find a natural way 
to make it hierarchical). It will make more and more sense as people 
seem to be favoring single hierarchies these days. (granted, not a 
settled discussion, so your views may vary)
