Smells like a fix didn't get forward-ported somehow -- that looks like
the same error I helped Tim find and fix for Zope 2.

CC'ing the ZODB list just in case anyone there has a better memory.
Here is the NEWS.txt entry for that fix:


 DemoStorage
 -----------

 - (3.4a4) Appropriate implementations of the storage API's
   ``registerDB()`` and ``new_oid()`` methods were added, delegating to
   the base storage.  This was needed to support wrapping a ZEO client
   storage as a ``DemoStorage`` base storage, as some new Zope tests
   want to do.
