> The {{SlotManager}} can reach an inconsistent state when a formerly free task slot is reported as allocated by an incoming {{SlotReport}}. The problem is that the slot won't be removed from the set of free slots and, thus, will be considered for future slot requests.
> The solution is to remove the slot from the set of free slots once it is reported allocated.
