[Grok-dev] Pickling an object stored in the Zodb. How do I skip the __parent__ attribute?

[Sebastian Ware]

I am trying to export and import objects from the Zodb using  
cPickle.dumps().

My problem is that the pickler traverses the __parent__ attribute thus  
returning a much larger object graph than I wish to serialize.

Do I have to subclass the pickler or is there som other smart way of  
making it skip the __parent__ attribute?
