> In case that the {{JobManager}} dies without notifying possibly connected {{JobClientActors}} or if the job execution finishes without sending the {{SerializedJobExecutionResult}} back to the {{JobClientActor}}, it might happen that a {{JobClient.submitJobAndWait}} never returns.
> I propose to let the {{JobClientActor}} periodically check whether the {{JobManager}} is still alive and whether the submitted job is still running. If not, then the {{JobClientActor}} should return an exception to complete the waiting future.
