should have included that all timings are consistent.
(usr/sys vs reported wall clock time vs external stop watch time)

for reference: the effect arises for a several different memory types
(pc133, pc133 ecc, pc133 reg ecc, pc2100) and the impact is similar.
thus if it was only a memory bandwidth issue, i would expect
the results to depend more on the memory/chipset in question.
