|

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.
