Research direction

Start by reading the historical redcycle.diff and issue1062277-test-py3k.diff attachments, then review superseding issue bpo-9269. Determine the current expected behavior for pickling recursive structures and whether this issue remains distinct; done means the agreed behavior is covered by appropriate regression tests and the superseded work is not duplicated.

Written by the indexing model from the issue text.
