James Peach commented on MESOS-7963:
------------------------------------
As per discussion with [~jieyu] the right fix here is for the containerizer to
propagate the container limitation to the {{WAIT_NESTED_CONTAINER}} response
when it destroys the nested containers. Then the executor should pass that
information on in status updates. Though there will still be a race between the
executor and the agent, both parties will still end up propagating the same
status update information.
> Task groups can lose the container limitation status.
