Several people have pointed out the fact that the SUN machines use
50 Hz and thus my changes don't work quite so well on them. One
could just change the #define, but a more "elegant" method is
to open /dev/kmem and burrow through the namelist to find how
fast the timer really ticks on that machine.

I'll spare you the details of figuring out how to do this.  When I
get that far (if ever), I'll just steal the appropriate code from
"gprof" which figures the clock rate in just this manner.
