  Note that:
    - a lot of the processing cost in Norman stylesheets comes from
      the "chunking" code, if you generate flat files it's quite faster
    - a lot of the time spent is also related to parsing the DocBook
      XML Dtd, and this could probably be factored if you keep a 
      background daemon in charge (though I don't have currently an
      API for doing this, reusing a parsed DTD is definitely possible).
