WCPU is supposed to be weighted in some way to take swap time in to
account. It's possible that the weighting calculation is adding a bit to a
nearly 100% value. Try displaying just %CPU (the 'C' command I think?) and
see if it is reporting over 100% for a normal (non-weighted) cpu percent.
It shouldn't. If it is, then there's something weird about the way the
value is being tracked by the kernel.
