Ok, it looks I have to create that attribute.  Now, the next confusing
part is that the documentation says: 'If it [find_global] is None then
any attempts to unpickle instances will raise an UnpicklingError.'  What
exactly is considered an instance in this context?  I tried unpickling a
dictionary, and it unpickled just fine.  Please, someone explain :)
