That is a good question. I think I noticed various grab functions but
missed XGrabServer. Or maybe I noticed it but wasn't sure if I could
trust it. I will revisit these manuals and try again..

I didn't realize composition managers are that mainstream yet :-) Is
there really no way to draw to the screen if a composition manager is
frozen (due to grab or frozen unix socket)?

What if I'd make the composition manager co-operate and temporary
return the X to "do not use composition" state?
