+        self.entries_changed = False
+        self.entries_deleted = False

I suggest calling them any_entries_*, like in the existing code. 
Otherwise I'd expect them to be something like a list of the 
changed/deleted entries.

I see Ian read the rest of it and you answered my question on irc, so 
I'll leave it there.
