Interactions all run inside a db transaction, I think (someone please
correct me if I'm wrong).  So if your DB supports transactions, then you
should be fine already.  I'm presuming that by "interaction" you mean
twisted.enterprise.adbapi.Augmentation.runInteraction?

So already we have legacy systems to support :)

I'm not aware of any significant changes to twisted.enterprise since
0.15.2.
