   If you don't do enough port to get the OS running in the native
   instruction set, then performance is crap.

   And the easiest way to get that much port done is first port the
   thing to the hardware.  VMS doesn't have a lot of code to support
   sitting on HPVM instead of naked Itanium, and doesn't have a
   lot of dead code in that environment, either.
