I have also seen the same result on sparc64 and amd64 kit, I have
looked into it a bit on google and the general feeling is that the WCPU
(or weighted CPU) count is not all that accurate.
A more accurate representation can be obtained by passing the -C flag
when starting top. This is for raw CPU rather than a weighted average,
on some quick tests on a V120 whilst running buildworld I have not seen
a reading above 100%.
