Python weakrefs are not pickable so ZODB doesn't support them.

ZODB has it's own wekref implementation.  I added it in preparation  
for work on persistent interfaces.  I wish I hadn't,  I doubt anyone  
is using that.

ZODB cross-database references have wek semantics. This is not very  
popular. :/
