> There are cases where Akka quarantines remote actor systems. In that case, no 
> further communication is possible with that actor system unless one of the 
> two actor systems is restarted.
> The result is that a TaskManager is up and available, but cannot register at 
> the JobManager (Akka refuses connection because of the quarantined state), 
> making the TaskManager a useless process.
> I suggest to let the TaskManager restart itself once it notices that either 
> it quarantined the JobManager, or the JobManager quarantined it.
> It is possible to recognize that by listening to certain events in the actor 
> system event stream:
