> In case that the TaskManager fatally fails and some of the failing node's
> slots are SharedSlots, then the slots are not properly released by the
> JobManager. This causes that the corresponding job will not be properly
> failed, leaving the system in a corrupted state.
> The reason for that is that the AllocatedSlot is not aware of being treated
> as a SharedSlot and thus he cannot release the associated SubSlots.
