in thread Does IO::Select work? Anywhere?

Really, removing socket from IO::Select is the smallest thing that should be done before socket is closed. In practical life there's whole bunch of other stuff that should be done as well. For example: release data associated with the connection, notify the user that connection is closed (log it at least), possibly schedule establishment of new connection and so on.

Actually, you are wrong again. None of those things have to happen before the socket is closed. Those are things that might (in theory) be desirable to do around the time that the socket is closed. None of them are things that are likely to just silently do nothing if the socket got closed before them (unless you implement them stupidly... like IO::Select).

Well, I live in real world and in 10 years of network programming I haven't run up into situation where the behavior of IO::Select would be a problem for me.

"would"? So, in theory, you don't think you'd have run into this problem. That's hilarious.
