When I first heard of x32, I thought it was a joke.
I still think it's a joke and I'm glad someone put
effort in writing such a good article on why it might
not be such a hot idea after all.
It's a crazy idea that will prove itself to be stupid.
No one will use x32, except Intel to run some hand picked
benchmark now and then. And then it's stuck in the kernel
for backward compatible reasons forever.
