Just wondering: how urgent is this fix? Is this something we should try
to get into 7.3 given that this was noticed in a regression report that
blamed it on an 7.3-rc commit[1]? That commit also made it to many
stable series now, which might be another reason to get in mainlined
rather sooner than later.
