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
always.

Best,
