Your description reminds me of several years ago when I was doing the Dow-Cells stuff. I don't know the openGL demos at all, but I don't see why you expect a REPL while a demo is running. I haven't seen a graphics demo yet that leaves me an active REPL. I too was told that I needed 'good threads' for that cells project, but I found that the simple telnet to the running image trick to be sufficient, add it with the built-in MP package. (setf mp::*idle-process* mp::*idle-process*) (mp::start-lisp-connection-listener :port 7001 :password "foo") ...get telnet REPL setup... ...graphics stuff... If you want to update the running code (in some loop, as a graphics process would be) an ordinary telnet works fine. Nowdays, you can start another slime-listener. I have no idea if this will work for your needs, but it is simple to try it. r
