Why can't you get the number of the initial results before fetching them
page by page?  If you create an initial query and save it as a view, why
can't you grab the number out of that first result set (via a ntuples
function call or by executing an SQL statement), then page through it with
your cursor?  Or can cursors not be created from views?
