        //     therefore synchronizes-with the previous poll's `Release` store,
        //     ordering that poll's writes before ours.
        //
        //   - Woken while running: the previous poll's `compare_exchange` failed
        //     (the state was already `WOKEN`), so that poll rescheduled the job
        //     itself. Its writes are sequenced before its `schedule` push, which
        //     the job queue orders (`Release`) before this poll's dequeue
        //     (`Acquire`).
