Ok, I understand if that is the current goal, but I think the Right
Thing should (1) behave in a sane way if the X server is kill -9:ed
(i.e. cleanup bound to a no-senders notification somewhere), and (2)
support arbitrary frame buffer applications in a simple and robust
way.

I.e. the responsibility for sane gfx state should be in some
privileged process. A non-privileged user should not be able to shoot
it down (but he should still be able to kill his own X server, and
certainly his fb applications, and perhaps even his own console).
