   AFAIK, the main problem with SASOS is "backward compatibility", most   
   importantly with `fork`.  The Mill people proposed a possible solution,   
   which seemed workable, but it's far from clear to me whether it would   
   work well enough if you want to port, say, Debian to such   
   an architecture.
