I think this could well be something to do with my original problem. The
score sorts just fine, but dies while rendering. Since the score is
basically just a collection of randomly distributed sine blips that gets
less and less dense over time, and since it's more or less at its densest
when it falls over, that could well be where the bug (feature?) lies.

I'd guess it's trying to start another instrument, runs out of its memory
allocation, starts overwriting stuff and then falls off the edge of the world.

Could be completely wrong of course...
