[Zope-dev] BTrees and Persistance

[Yair Benita]

That is of course true, I only change the set and would like to save 
the information.
Trying T[1]._p_changed = True gives an error:
AttributeError: 'set' object has no attribute '_p_changed'

so the only way to do it is to set _p_changed=True for the Tree.
Does that mean that the entire Tree object is rewritten to file?
