	Frame and Render is not a useful distinction
	cycle or loop or step instead of frame?
	draw instead of render?

	we keep combining the two, and it's not a good idea
	as input can be polled at a higher frequency than rendering can be output?

	Hertz & Frame

	does a process ever not have a GUI? *can be hidden &| locked
	we are trying to skip the tty!

	would be nice to have a dedicated thread(s)
	for essential GUI
