Looking at the IO graphs I believe the planet.rb script is moving very
slowly because DB is completely IO bound. I suspect the 30 minute CPU
blips occur each time the planet.rb successfully fetches another page of
500,000 entries.

I guess it will start moving more rapidly again when the other DB/API
users start to drop off after midnight.

I'll try to find some time to see if the planet.rb script or SQL queries
can be made more IO efficient.
