I hadn't understood your nosimd=1 command line suggestion the first
time through, but now I see what you were after. This would be really
easy to add. And I can do it for v5 if you want. But I'm kind of loath
to add too much stuff to the initial patchset. Do you think this is an
important feature to have for it? Or should I leave it for later?
