JIT is a good technology, but it's limited to interactive debugging as the
name says. I've had people email me 100MB core dumps and that was the only
way I could find certain problems that needed certain OS environment etc
that I just couldn't reproduce.

I believe JIT technology is capable of supporting these "post-mortem dumps",
but it's a lot of work to get it right.

I like core files. No wait, I hate core files ;-)
