I don't know if people realise that Cray's don't have an MMU, they
use fences. From my intern days at Cray I know this made life a
living hell for the OS dudes trying to get UNIX(tm) to work right
on the 2's, X's and Y's. Obviously they found ways around the lack
of a traditional MMU but look at our kernel and how much it depends
on a run of the mill MMU and I think the NetBSD/Cray port might
cause premature pattern baldness...
