> When allocating slots for eager scheduling, it can happen that allocated
> slots get failed after they are assigned to the {{Execution}} (e.g. due to a
> {{TaskExecutor}} heartbeat timeout). If there are still some uncompleted slot
> futures, then this will not be noticed since the {{Execution}} is assigned to
> the {{LogicalSlot}} only after all slot futures are completed. Therefore, the
> allocated slot failure will go unnoticed until this happens.
> In order to speed up failures, we should directly assign the {{Execution}} to
> the {{LogicalSlot}} once the slot is assigned to the {{Execution}}.
