使用socket.core.tcp以非阻塞方式去读当前socket中的数据时，会返回nil
在源码
https://github.com/dualface/v3quick/blob/v3/external/lua/luasocket/buffer.c#L210#L221处，是不是要对IO_TIMEOUT进行判断，比如：

    if (err == IO_CLOSED) {
            if (total > 0) return IO_DONE;
            else return IO_CLOSED;
    } else {
            if (err == IO_TIMEOUT && total > 0) err = IO_DONE; 
            return err;
    }

如果理解有误请见谅。
