Do something smart on line 346 for on the fly counting. Though I think
that I can generate the page that you provide maybe faster using just
group by on an existing database... MonetDB uses string deduplication,
perfect for this job ;)

So that answers your:

"So what I'm looking for is a simple (I really don't want to have to
setup another Hadoop cluster) but still reasonably performant way to
process the planet.osm to aggregate the needed data in a suitable
format for importing it into a relational database."
