Funny that you ask now. Jim implemented a version recently that is
slated for ZODB 3.3. It's in CVS, perhaps on a branch, but was not in
the last alpha release.
Can you tell us about the use cases for weak references? A persistent
weak reference is a bit of an odd thing. It doesn't go away until the
object is unreachable in the database (as opposed to unreachable in the
current process). Is that what you had in mind?
