> When the {{JobManager}} receives a {{JobStatusChanged}} message, it will look 
> up the {{ExecutionGraph}} for the given {{JobID}}. If there is no 
> {{ExecutionGraph}}, then a {{RemoveJob}} message is sent to itself. In the 
> general case, this is not problematic, because the {{RemoveJob}} message 
> won't do anything if there is no {{ExecutionGraph}}. However, since this is 
> an asynchronous call, it can happen that the corresponding job of the 
> {{JobID}} is recovered before receiving the {{RemoveJob}} message. In this 
> case, the newly recovered job would be removed.
> I propose to change the behaviour such that a {{JobStatusChanged}} for a 
> non-existing {{ExecutionGraph}} will be simply ignored.
