I'd like to upload current master to debian experimental.  I think this
might help with a few integration issues (libgmime in particular, and
maybe gpg-agent).

My branch is at 

   http://pivot.cs.unb.ca/git/?p=notmuch.git;a=shortlog;h=refs/heads/proposed-0.5.5

On top of current master, this includes some packaging changes, and the
previously posted patch that adds a timout to the tests.

Any comments are welcome.

David
