I should also mention to clarify further, I have the use case where the 
instances I load are effectively all detached from any session. I do this 
intentionally as it feeds my WPF application. Then when I am ready to save 
after some changes have been made to the instances and constituent 
collections, I would reattach all to a new session. There are moments when 
that happens when the composition of collections would then be different. 
So there needs to be some reconciling between the two. I had to take some 
steps in countermeasure with EF apparently; not sure if FNH is any more or 
less transparent under those conditions.

Thanks!
