[Zope] custom_persist_obj

[Paul Winkler]

Well, sure. But you need to write some unrestricted (i.e.
filesystem-based) code if you want to create instanced of
PersistentMapping and the like.

by the way, if it's ever going to get large, you might look
into using OOBTree instead of PersistentMapping.
