So, I install a signal handler with installHandler... and then ? how do I prevent the program for quiting ? am I missing some kind of event loop here ?

Here is a small server program: main = performForkWithUnixySessionStuff work -- this is just for testing, replace with real implementation performForkWithUnixySessionStuff x = x work = do s1 <- runStreamServer ... s2 <- runDgramServer ... mv <- newEmptyMVar installHandler someSignal (Catch (putMVar mv ())) Nothing takeMVar mv someCleanupActions killServer s1 killServer s2 For simple testing you might want to just use getLine to wait for the right time to exit. - Einar Karttunen
