If you have a function along the lines of this one:

    def someInteractions(db):
        interactions = [

Then a failure in one shouldn't affect two or three; likewise for any 
other failure or combination of failures.  They are naturally (ugh, not 
a good word, but I can't think of a better one) independent.  You have 
to go out of your way to associate them somehow.

Since it sounds like this isn't the behavior you're seeing, I think I'm 
probably misunderstanding some aspect of your question.  If this doesn't 
help, perhaps you can clarify?
