My first reaction to this is "eeck." Not because you code is bad -- it
looks reasonable -- but it's something that I had kinda hoped I could
get away with TileCache not doing, simply because it adds more
complexity.

I'm not sure what I want to do about this. I want to turn it over in my
head for a bit.

If you don't see action on this, poke me in a week or so, as I'm likely
to have forgotten.
