超时断开逻辑是不是有问题？

server在poll到连接新的事件时，貌似没有更新连接的超时时间。

Thanks for pointing this out. Indeed I think I forgot to refresh the timer for a client connection when new messages arrive.

I have cooked up a patch here for your reference. [commits]

I hooked the refresh functionality together with customer-provided handler function, so that when a new event arrives for a client connection, the first thing it does is to refresh its timer.

And thanks your observation, I even find a subtle lifecycle race problem as in #39.
