     * This test case demonstrates an issue with the identity case in the
     * Doctrine_Table class.  The brief summary is that if you create a
     * record, then delete it, then create another record with the same
     * primary keys, the record can get into a state where it is in the
     * database but may appear to be marked as TCLEAN under certain
     * circumstances (such as when it comes back as part of a collection).
     * This makes the $record->exists() method return false, which prevents
     * the record from being deleted among other things.
