The overwhelming majority of the d.o downtime has been from a slammed
DB server. For the server side of update(_status?).module, the DB is
only touched once every 6 hours to regenerate the .xml files for the
release history for each project. These queries don't show up in the
top N list of most expensive queries on the DB server. To actually
serve the history, there's no Drupal bootstrap at all, just an ultra-
thin PHP wrapper.

responsible at all".
