Yes it does. It just doesn't make *good* use of it - in fact
performance is likely to be worse than on a uniprocessor
machine, as the python process may frequently bounce from one 
processor to another.  Read that thread again.

What's needed is a way to *prevent* python from using more
than one processor, so you can run one (or more) instances
of Zope per processor and bind them to that processor.
This depends on the OS.  IIRC Solaris can do this,
but Linux out-of-the-box cannot.
