I run a very simple joystick server that writes its position to a port, say, 50005, so that (a) multiple clients can connect to the stick (b) I can run a fake server on machines without a stick and continue to test programs that need to read a stick. When I kill the server, I find I often can't restart it on that port, but can on, say, 50006. I'm guessing that some resource stays around until it's killed off, usually after less than a minute. I intend making my server pick the next free port, and likewise the clients will have to play chase the server. Meanwhile I don't worry.
