Yes, it was reason a).  Transactions aren't automatically invalidated
after an IntegrityError, as far as I was able to determine.

Hmm... I can't figure out if this will post a reply to the whole group
on this discussion from the Google Groups API.

Anyways, I just wanted to say that I love django-flash. "The flash" is
just the Rails term for user messages and has nothing to do with
Flash. Doing a search for "django flash" is much more helpful than
"django user messages."

I've been using it on Baconfile and it's hot.
