Has anyone gotten glut:main-loop to work in it's own thread ? I'd like to be able to asynchronously execute opengl calls while the main loop is running. I have a bit of a hack that can do this in effect, by calling glut:leave-main-loop inside a callback, going the repl and running list and then manually starting the mainloop again to refresh, but it would be nice to use threaded main loop. I'm using sbcl on mac OS, so I am not even sure if threading is going to work.
