  * massive convulsion in ZipDataflow
  
  After my talk, I got the idea of 'shallow rewriting' for the
  dataflow framework.  Here it is implemented, along with
  some related ideas late making Graph and not LGraph primary.
  
  The only bad thing is that the whole bit is stitched together
  out of ill-fitting pieces, kind of like Frankenstein's monster.
  A new ZipDataflow will rise out of the ashes.
