Well, in fact what I meant is: I won't to check wether established
connection is still active. I have a reading thread and when I send 'quit'
command to a server it (guess what:)) disconnects. So I get plenty of
unwanted output, I want to avoid this. So the problem is how can I inform
my reader thread it is not longer wanted when _server_ disconnects me? To
my defense: repetition is mother of science (in case you did answer and I
did not get it first time).
