    Yes. Thanks for pointing that out. :)
    I was earlier doing things a little differently. Forgot to fuse them.

> 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.
