---------------------------------------------------------------------

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.
