I'm not a die-hard X11 hacker, but I guess that when you just draw a
full-screen appliation while calling XGrabServer(), you can already
implement something like that. But that's evil, I guess, because then
you don't offer graphical applications to flush their work to the
display, which will cause them to stall.
