When using Sockets, exactly when and where do I have to close them? The documentation (of module Socket) implies that this is not necessary? However there is sClose in SocketPrim. My application is one Server who runs `listenOn' and many (short lived) clients that `connectTo'. After I run this for a while, netstat typically says autotool@isun11:~/autotool/serial$ netstat|grep local localhost.9121 localhost.56749 32768 0 32768 0 CLOSE_WAIT localhost.56749 localhost.9121 32768 0 32768 0 FIN_WAIT_2 localhost.9121 localhost.56753 32768 0 32768 0 CLOSE_WAIT localhost.56753 localhost.9121 32768 0 32768 0 FIN_WAIT_2 although some seem to vanish after a while (some minutes).
