I wouldn't go that far yet.
Do I understand this right that the future readahead code needs separate
behavior depending on whether a cursor is scrollable? I would think
that whatever you do with NO SCROLL cursors would also work with SCROLL
cursors, so if you don't know what the cursor is, just use the code for
NO SCROLL.
