As Timothy pointed out and I should have known, currently there is no window-level security for X programs. So we just mmap video memory, provide a way of flushing the render pipeline, and we're done. We should however, keep the window security question alive as a background project. To me, it looks like a bleeding wound in X. Doing something about it would be a worthwhile long term project.
