This indeed seems like a good candidate since likely the current
sequential code can't be sped up much. Can someone tell me where in the
code the parallelization should take place? Perhaps the while loop
inside LoaderQueue::loadNext() ?

By the way, I've sometimes wanted a more aggressive graphics loader. I
think it's pretty impressive how it currently works and converts things
on-the-fly with scrolling, but I would like to be able to say "don't
wait for me to scroll, just start converting after I open the .lyx
file". I know that would involve a lot of wasted cycles, but sometimes I
would prefer that.

Good to know.
