完全正确

自己嚕的TCP over TCP已踩到這問題...
改成每個stream一個token
加入2個控制封包: full, empty
這樣是否會比較好?
正在改寫中
如果完成後沒問題會提交PR

@cs8425 不清楚你说的每个stream一个token怎么实现，你又无法预知下一个strream id是什么的时候

@xtaci
目前大致構想是這樣的:
廢掉Session的token bucket
Stream結構裡面加入token
Session的recvLoop(), cmdPSH的時候檢查Stream的token(假設為A端)
不足的話傳送stream id + full到對面(假設為B端)
block住B端那個stream id的Write
直到A端Read夠多的資料出來(token夠多了)
A端傳送stream id + empty到B端
讓B端的那個stream可以繼續Write
不知道這樣會不會有什麼問題就是

这样stream越多，内存用量越大

是的
理想情況下可能還需要一個機制來控制最大同時連線數
不過理論上來說
除非夠多的stream都很慢
而且對面沒收到控制封包block住Write操作
否則記憶體用量應該是可以接受的
