What you may be thinking of is the ability which currently
exists to "buffer" a series of communication; eg, in maphand.c

void send_all_known_tiles(struct player *dest)
{
...
      connection_do_buffer(pplayer->conn);
      for(y=0; y<map.ysize; y++)
        for(x=0; x<map.xsize; x++)
          if(map_get_known(x, y, pplayer)) {
            map_clear_known(x, y, pplayer);
            light_square(pplayer, x, y, 0);
          }
      connection_do_unbuffer(pplayer->conn);
    }
}
