I think "because I suck" is probably the right answer :)  When I
originally wrote the code, that's what I came up with.  I had problems
finding useful examples and documentation so in the end I just
experimented until I found something that worked.

Incidentally, previously in places I was calling db.cursor.fetch_one(), in
a case where I needed to test each row before deciding if I needed more
(with a test I couldn't implement in SQL).  Now db.cursor has gone, how
can I do this?

It seems equivalent in performance - we've got some very complex queries
and they took around 6 or 7 seconds to execute, and they still do :)
