NetConn leaks timers

[ash2k]

Hey, first of all thanks a lot for NetConn()! I have written one myself, but then discovered this library and decided to use it instead.

I have noticed that netConn.Close() does not call Stop() on writeTimer and readTimer. I think it should at least if the deadlines have been set. Otherwise these timers are lingering around and that can be an issue if there are a lot of connections.

Great catch! Will fix soon.
