Title: Fix issue 8085

This change makes joiner not assume anything about the persistence of .front. I know there has been no consensus on the transience issue yet, but this change is harmless and makes the code more robust, so I'm submitting it. Plus, it lets us close issue 8085 sooner, regardless of how the transience issue will be decided on.
