I expect it's the driver doing cursor work for you without you
needing to make it happen explicitly.  I think some interations of
the JDBC driver do something similar, but I can't recall for certain
(and I'm not looking at the docs right now).  Anyway, if it _is_
doing a cursor for you behind the scenes, that's almost certainly
what you want.
