As Steffi said, currently not at all, but for potentially paging
containers to come, always. In any case, on deletion of the
container/image itself, the cursor-external references to the access
pages are gone. That is, when you close the image/container, you do not
have to close the cursors working on it before nulling them. Otherwise
