Yes, they are indeed different! However, my tests suggest it's not an
issue with TT stash cloning. Using refaddr, I can watch what happens
in my controller, and they're distinct before they ever get to the
stash. Apparently CDBI can't see the Prefs object that's referenced by
the User object that's stored in the catalyst session object. I'm
suspicious of the session object, bc I've been able to replicate this
behavior with another class, just by sticking it into the session
object.

For sanity's sake, here's the sequence:

User logs in and User object is saved to session
User has a prefs object
User wants to edit prefs
Prefs object is retrieved from db
Prefs object is updated
User->prefs is not refreshed
