xtar_load.

Changes all over the place seem to occur only in SMP with much smaller changes
in the UP results. If you look at the detailed results you can see very large
variations in run times for the io based loads (io loads, tar loads). It was
so different that the dbench_load changes so much it's not worth doing them
or reporting them. I'm not sure why the io based loads vary so much more in
SMP mode.
