That's a little different than what Andrew was describing as
"multi-core," though.  His definition was that it was exactly the same
as having that many separate CPUs.  Sun's definition in the new
UltraSPARC chips is separate ALUs but other resources are not
duplicated.  Perhaps most notably, there is only one floating point
unit shared between all of the cores on the chip.

Personally, I don't think there's a strong enough argument for one
definition to be "right" and the other "wrong," so you just have to be
aware which one you're using.
