That should work on most platforms, but it's safest to have all the
graphics stuff in the main thread and the other things in their own
threads. You also need to make very sure that you're only doing
graphics stuff in one thread, because some OpenGL implementations go
absolutely drugged-squirrel psycho if you don't.
