[Checkins] SVN: Zope/trunk/ Fixed ``testZODBCompat`` tests in ZopeTestCase to match modern ZODB semantics. There is no explicit contract for the time _v attributes actually get removed. The tests in question where bogus, as they didn't test database load but a class variable not affected by the transaction machinery. There's other tests in the same module testing more abort semantics that have a proper demo storage setup.
