+When cyclic garbage collection (gc) runs finalizers that resurrect
+unreachable objects, the current gc run ends, without collecting any cyclic
+trash.  However, the statistics reported by ``collect()`` and
+``get_stats()`` claimed that all cyclic trash found was collected, and that
+the resurrected objects were collected.   Changed the stats to report that
+none were collected.
