The difference is that the interface of my proposal seems (to me) more
in line with the general cursor-based model of DB API.  It only adds
one more function, and everything else happens naturally -- for
instance, you still execute statements through cursor.execute,
retrieve rows through cursor.fetch*, etc.

Everyone please note that my proposal comes from a mere *user* of the
DB modules.  If what I propose is hard to implement, don't hesitate to
let me know.
