---------------------------------------------------------------------
We are investigating an issue BEAM-8651 where Python 3 pipelines _sometimes_
fail with pickling errors in StockUnpickler.find_class(). Positing it here for
visibility since it seems to be common in certain execution scenarios.
Note that this is different from
[BEAM-6158|https://issues.apache.org/jira/browse/BEAM-6158?focusedCommentId=16919945&page=com.atlassian.jira.plugin.system.issuetabpanels%3Acomment-tabpanel#comment-16919945],
which causes _consistent_ failures in StockUnpickler.find_class, when
--save_main_session is used and main module has super() calls.
