What's particularly irritating is that http://labs.metacarta.com/osm is
rendering mapnik tiles on demand, not queueing them for later, meaning
that the whole world can be seen at any time but problem it is using
really out of date planet.osm data and cartography styles, and there is
a small map projection issue, which I'm not sure has been resolved.
