no, I was not kidding, I fetch a row per call. I know it could be done
quicker by using threads, but at the time I coded that, I didn't want to
use threads.

Although I think you're right that it may be slow, so I'll change it to
get more rows in each call.
For the gnome 2 version, I'm moving it to use threads instead.
