> 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}}.
