> For partially managing textures on impl thread, that's tricky and not sure what the best solution is there... Best I can think of would be to have flags on each texture (eg 'visible') that are pushed to the impl thread

This was what I was thinking with this patch -- the flag would be stored somewhere in the opaque structure and then sent to the impl thread.

Then Dana pointed out that the priorities are only updated and sorted when the main and impl threads are at their sync-point.  Because this is the case, I can safely read through the priority list in the impl thread to decide what to kill.
