I ran the coastcheck utility last night to update the coastline
shapefiles on the main Mapnik layer.
The updates will not automatically appear on the map unless the tiles is
re-rendered due to updates of other data. We have no mechanism to
recognise which tiles need to be rendered when the coastline is updated.
This is part of the reason why the updates are normally coincident with
the bulk reload where we mark all the old tiles as invalid.
