> If a container is killed while localizing then it releases all of its resources.  If
the resource count goes to zero and it is in the DOWNLOADING state then the resource bookkeeping
is removed in the resource tracker.  Shortly afterwards the localizer could heartbeat in and
report the successful localization of the resource that was just removed.  When the LocalResourcesTrackerImpl
receives the LOCALIZED event but does not find the corresponding LocalResource for the event
then it simply logs a "localized without a location" warning.  At that point I think the localized
resource has been leaked on the disk since the NM has removed bookkeeping for the resource
without removing it on disk.
