Review request for mesos and Benjamin Hindman.


Repository: mesos-git


Description
-------

This isolator only creates the perf_event cgroup and places the executor into 
the cgroup; no performance statistics are gathered/exported.

NOTE: The recover() as implemented is "non-strict"; it will happily recover 
containers even if they don't have a perf_event cgroup present. This permits 
restarting the slave to add this isolator. Existing containers will not be 
isolated. New containers will be isolated.

Testing
-------

Manually tested.

Our current testing code does not easily permit testing different combinations 
of isolators for the MesosContainerizer.


Thanks,

Ian Downes
