func (server *Server) ServeConn(conn io.ReadWriteCloser) {
	defer func() { _ = conn.Close() }()
    // ....

}
func (server *Server) serveCodec(cc codec.Codec) {
	sending := new(sync.Mutex) // make sure to send a complete response
	wg := new(sync.WaitGroup)  // wait until all request are handled
	for {
		//...
	}
	wg.Wait()
	_ = cc.Close() // 这里
}

gobCodec的close 直接调用了conn.close
这里好像多次调用了conn的close?

stackOverflow的讨论

似乎这样会出问题，我想应该有两种解决方案

把codec的close都实现成幂等的
把ServeConn的Close去掉

希望解惑谢谢
