   OK. I'll rephrase that. None of the processors I've used in the   
   past...  It appears later SPARC and ARM chips are variable too. I   
   expect to be using ARM in the near future.   
      
   But it's still a problem best address during I/O; the cost of   
   translating once on the way in and once on the way out is likely to be   
   many times less than the cost of translating on the fly during   
   processing.
