I was referring specifically to the memcg which a job scheduler or 
userspace daemon responsible for doing so is attached.  If the thread 
responsible for managing memcgs and increasing limits or killing off lower 
priority jobs is in a memcg that is oom, there is a chance it will never 
be able to respond to the condition.
