The notion of "SMT (Simultaneous Multi-Threaded)" architecture has been
there for a while (at least 8 years, as far as I know). You would get tons
of info if you search it in Internet.

"thread" already has another use.  Let's not let the idiocy [most 
likely] perpetrated by marketing folks to filter down to the useful
