> [~mingma] pointed out in the review discussion for MAPREDUCE-5465 that the NM is currently
sending out of band heartbeats only when stopContainer is called.  In addition those heartbeats
might be sent too early because the container kill event is asynchronously posted then the
heartbeat monitor is notified.
