That is all I (or rather, the book) is claiming. I am not implying that
they ever shared code.

Well, I will have to go and find the book (which could take a long time),
but I am pretty sure it was a major design goal for that version (AIX 3, I
think?), and as I stated, was ported to other architectures that are
not very POWER. If the book is misleading - well, then I have been
misled. However, it is an official IBM document.
