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. > If you could bisect the Org file and narrow down the crash to a smaller > example file that would be wonderful.

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. > Btw, I find the use of "theoretically" a bit inconsistent in your > email.

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.
