Tom, forget this.

Remember that I have a dual 2.8 xeon that didn't exist when I was producing
numbers on it.  Vincent was _adamant_ that no dual 2.8 xeon with SMT was
available.  Even when I was posting log files from the machine.  He can't
read, and somehow concluded that only PIV's at 3.06ghz and beyond had SMT.
He didn't notice that _all_ PIV xeons had it, but non-xeons only had it if
they were 3.06 and faster.  yet he stated his wrong reading as fact, and
called everyone with xeons liars if they claimed to have SMT working.

There's little point in arguing with someone like that.  I gave him the
serial number of my machine, and told him how to order one from Dell if he
really thought it was fiction.  Others ordered them and ran them, even though
they "didn't exist".
