 I have an automated package build set up using Hudson, and it tries to
 build my code as often as once every 5 minutes.  Right now, that means
 running cabal update before every build, which takes at least 30 seconds.
 It would be great if cabal update used the ETag and If-Modified-Since HTTP
 headers to do conditional fetches of the metadata, so that there would be
 far less of a performance hit to both the Hackage server and my client.
