Granted, such benchmarking will give us a feel for how well NetBSD & gcc
are doing at using VAXen cycles.  For a more formal result, the SPEC info
may also be of interest.  I've left in some Intel related stuff as that
tends to cover the experience of others (i.e. for comparison, presuming
it is not silly, even with SPEC results, to make such comparisons...).
