      Once every page of the new generation has committed, delete all pages whose gen_id is lower than the one just written.

      • Lower gen_ids only: a higher gen_id may belong to another writer that is still writing it.
      • Also removes partial generations left by failed or interrupted writes.

      See WRITING-11150, ANNEX II.
