Ugo, would you please produce a page documenting your approach to this
for the Wiki. Other people will also need to know this stuff.

Well, not currently. Occasionally other people have requested things
like Session.refresh(), which I have stubbornly not implemented because
I never saw a really compelling use case. ( *This* is a good use case
for refresh(). )
For Hibernate 2, should we add one or both of:
Session.evict(foo); //remove foo from the Session-level cache
Session.refresh(foo); //reload foo's state from the database
There *would* be some exotic cases (like this one) where they could
be useful....
