It's a darn good thing the military doesn't use Intel stuff for their
digital flight control or weapons control systems. Can you imagine a
pilot cranking through a 9G turn when a message appears on the screen
saying "Please call Intel for your new FPU password".

Or how about an Intel processor running a respirator? Imagine the
anesthesiologist giving a patient a nudge, "Got a quarter, I have to
phone Intel for some more FLOPS".

Surely this isn't deja vu from April Fool's day?
