Perhaps not.  I'm still a little unsure how to handle all of the possible 
scenarios,  but I figure it will unfold as we progress.

The slowness isn't much of an issue for me locally, but I can say that 
performing many queries takes its toll.  One thing I've been using here quite 
successfully is a separately threaded class that actually handles the reads 
and writes.  QThread is used pretty sparingly throughout kdelibs, and I'm not 
sure if that's due to some specific reason not to want to use it, but it 
would definitely keep things lively while the queries were running.

Good.  I'll start working on taking what I've got and integrating it with the 
KConfig model.
