      Description

      Selector.completedReceives are processed using `forEach` by SocketServer and NetworkClient when processing receives from a poll. Since we may close channels while processing receives, changes to the map while closing channels can result in ConcurrentModificationException. We clear the entire map after each poll anyway, so we don't need to remove channel from the map while closing channels.
