> The root cause seems to be:
> * The "main" iterator reaches the end, so that the map, and the file, is
> closed.
> * But then, a "clone of the iterator" (not sure if that's the right word) is
> still open and tries to continue.
> * This fails because the map is marked closed.
> We need to keep the map + file open for a longer time.
