> Yury in the comment for PR 2108 [1] suggested more complicated code:

And this is still bad, because it loses the back trace. The way we do it is:

    do_something()
    try:
        do_something_other()
    except BaseException as ex:
        tb = sys.exc_info()[2]
        try:
            undo_something()
        finally:
            raise ex, None, tb
