I'll believe it when I see it <wink>.  Python's unpicklers in 2.3 still
contain warts to detect stuff unique to ExtensionClass-ish pickles, in which
case they try to call a __basicnew__ method that will presumably no longer
exist (in ZODB3 3.3).  Maybe ZODB's flavor of pickles don't trigger that,
though?
