Ok, brief testing and it seems to work; I'm not sure how to stress test
it though.

What I do notice is that back and depth both end up sitting in the
flushing list with RENDER write_domain when GL apps exit. I think that's
correct -- the 2D driver isn't doing any domain management, so the last
rendering from the terminating GL app will leave things sitting there.
That's validated by the IRQ request number being lower than the flushing
list reqno. I don't think this is bad though -- these are pinned
buffers, and so it's not a leak (freed buffers will be flushed and
waited for).
