> In order to plug in a different slot implementation, we should introduce a 
> slot interface which abstracts away the implementation details of 
> {{SimpleSlot}} wrt {{Execution}}. The reason this is necessary is to provide 
> a simpler slot implementation for Flip-6 since all allocation/release logic 
> will go through the {{SlotPool}}. Thus, we no longer need the concurrent 
> structure of {{Slot}}, {{SharedSlot}}, {{SimpleSlot}} and 
> {{SlotSharingGroupAssignment}}.
