[issue19021] AttributeError in Popen.__del__

[Richard Oudkerk]

Richard Oudkerk added the comment:

The clearing of modules at shutdown has been substantially changed in 3.4.  Now a best effort is made to let the module go away purely by gc.  Those modules which survive get purged in random order.

In 3.3 all modules were purged, but builtins was special cased to be purged last.  (See Python/import.c:PyImport_Cleanup().)

I would favour setting a flag before the purging stage which prevents __del__ methods (and weakrefs?) from running.
