You are assigning all the CPUs to the cpuset "all" and then making it an
exclusive/metered cpuset?

I dont think I am handling that case well (yet), primarily because usage of 
remaining tasks (which are not in cpuset "all", "mikeg" & "root") is not 
accounted/controlled. Note that those remaining tasks will be running on one of 
the CPUs assigned to "all". What needs to happen is those remaining tasks need 
to be moved to a separate group (and a runqueue), being given some left-over 
CPU quota (which is left over from assignment of quota to mikeg and root), 
which is not handled in the patches (yet). One of the reason why I havent 
handled it yet is that there is no easy way to retrieve list of tasks attached 
to a cpuset.

Can you try assigning (NUM_CPUS-1) cpus to "all" and give it a shot?
Essentially you need to ensure that only tasks chosen by you are running in 
cpus given to "all" and other child-cpusets under it.
