        C2 has a lot of places with the next calls sequence:

           add_users_to_worklist(old);
           hash_delete(old);
           subsume_node(old, nn);

        and without add_users_to_worklist(old).

        Investigate a possibility to call hash_delete() and add_users_to_worklist()
        from subsume_node().
