Hmmm. I don't think we store that information currently, though we could
for Feferreds. Anyway, there's a command in t.p.failure in CVS that
turns on extra debugging (the post-mortem thing). Call that and you will
have same functionaly twistd has in debug mode.

Given your requirements you probably don't want to be using twistd at
