> When the cgroups memory isolator is used Mesos will always try to enable the kernel oom killer by writing 0 to the memory.oom_control file. This will fail if memory.use_hierarchy is enabled on a parent cgroup, *even* if the oom killer is already enabled.
> We should attempt to enable the oom killer only if it is not enabled.
> This was observed on a Fedora 20 box which had memory.use_hierarchy enabled.
