I agree, nice work.

And it looks like FreeScreen is already doing the right stuff.

Might be nice to have the glx side also clean up at some point, but I'm
not sure where we'd stick that as we just use glXGetCurrentContext() for
that, and have no control over lifetime.

I think we're done here; this looks like a simple "thinko" to me.
