    Description

      G1DirtyCardQueueSet contains a mechanism for recording buffers whose contained cards were being refined, to pause that refinement processing for a pending safepoint. The (internal) protocol around this mechanism could be simplified by having record_paused_buffer() call enqueue_previous_paused_buffer(), eliminating the need for callers to ensure ordering of those calls. This would permit other improvements.
