> Now if we launch a docker container in Mesos containerizer, the racing may happen
> between docker daemon and Mesos containerizer during cgroups operations.
> For example, when the docker container which run in Mesos containerizer OOM exit,
> Mesos containerizer would destroy following hierarchies
> {code}
> /sys/fs/cgroup/freezer/mesos/<mesos-cgroup>/<docker-cgroup>
> /sys/fs/cgroup/freezer/mesos/<mesos-cgroup>
> {code}
> But the docker daemon may destroy 
> {code}
> /sys/fs/cgroup/freezer/mesos/<mesos-cgroup>/<docker-cgroup>
> {code}
> at the same time.
> If the docker daemon destroy the hierarchy first, then the Mesos containerizer would
> failed during {{CgroupsIsolatorProcess::cleanup}} because it could not find that hierarchy
> when destroying.
