Update of /cvs-repository/Packages/ZODB/tests
In directory cvs.zope.org:/tmp/cvs-serv25842/ZODB/tests
Change the exception raised when an attempt is made to add two objects to
the cache with the same oid. The former messsage didn't make sense.
Add a test to verify that this exception does get raised, and that the
message given is the intended one.
This is the first of a series of checkins, to fix critical bugs where
ZODB can in fact raise this exception in rare, but normal, use cases.
