ORM features should work without problems but you'll have to use the 'eager'
query mode everytime since retrieving stuff lazily means running queries for
attribute access and this is what you want to avoid for blocking reasons.

If you use fetchall() and the eager query mode for the ORM then SQLAlchemy
works as well (if not better) than other solutions. I save Axiom from this
because it has a particular attention to integration with Twisted (like
powerups and so on).
