[Openstreetmap] speed, at last

[Mikel Maron]

Yes, we should start caching OnEarth wms requests seperately. Soon.

The 300GB cache is a new format they're currently working on, so it's not mentioned elsewhere.
Advantage would be that we would never hit OnEarth again, and we'd have a static install, without a growing cache to worry about.

These 4 TB seem to contain a lot that we don't need.

So, my web browser gets tiles from tile.openstreetmap.org, which 
gets them from onearth.jpl.nasa.gov.  Are the raw tiles cached at 
OSM before adding white lines or yellow dots?  That would minimize 
our dependency on the NASA server.
