Reducing server resource utilization for busy sites by implementing fast 404s in Drupal

One of the things that a default Drupal installation does is that it handles 404s for static files within Drupal itself. In other words, a 404 for a .css or .jpg file causes a full Drupal bootstrap. This is not necessary, and wastes resources on a site that gets lots of 404s: lots of code is executed, many database queries are performed, only to return a 404 for a static file.
