The copy of dhrystone.c that I have defines the clock tick rate, HZ,
to be 60.  On the 4D machines this should be 100 (see
/usr/include/sys/param.h).  Using -O3 optimization, our 4D80 (16.7MHz
MIPS) clocks in at 29250 dhrystones/sec.  However, the whole question
is somewhat moot, since the dhrystone is a pretty worthless benchmark.

So now ya know.
