I don't want to use it that way, but I can check if it speeds it
up.... and it doesn't make any appreciable difference on the speed and
the crash still happens.

Is this useful information?

That sounds like a very good idea.

http://www.google.com/search?q=org-mode%20cache

Only tells me about the caching on the evaluation of code blocks, so
I'm not in a position to implement it, as someone who's never actually
used org-mode.

I mean that it seems appealing, but I have no idea because I've never
used it. I need to write a migration assistant before I could even
figure out if there was a benefit.
