If your ORM doesn't know about transactions, that doesn't necessarily prevent you from wrapping your test runs in transactions. I was in a situation where I needed to start / rollback a transaction without ActiveRecord knowing about it, and was able to hack AR slightly to make that work -- so you can likely do the same. You even mention in the Waterline section of that blog post that you've written your own transaction library, so this shouldn't be too hard.
