As a comment: with the recent changes in Mapnik to mmap shapefiles,
TileCache + OSM + Mapnik is probably a very poor path to take. The world
boundaries shapefiles are simply too large to reasonably expect to fit
into memory on most machines in a TileCache-like setup.

At this point, I think mod_tile is the way to go for OSM tile rendering
(much as it pains me to push people away from my own project). In Mapnik
0.4, it worked fine, but these new improvements, simply put, make on the
fly rendering of more than a handful of tiles (which TileCache doesn't
seek to prevent) impossible on all but the most powerful systems.
