Looks good!

Format it a bit, and push:

  {
    ShenandoahObjToScanQueue* q = _cm->get_queue(worker_id);
    ShenandoahSATBBufferClosure cl(q);

    SATBMarkQueueSet& satb_mq_set = ShenandoahBarrierSet::satb_mark_queue_set();
    while (satb_mq_set.apply_closure_to_completed_buffer(&cl));

    ShenandoahSATBThreadsClosure tc(&cl);
    Threads::threads_do(&tc);
  }
