With Jonathan Corbet's help the text should actually be readable. I had to change some of the text in the end to accommodate line breaks in the PDF. So I might have introduced problems, don't think bad about Jonathan's abilities. Aside, this is a large document. You simply go blind after a while, I know I do.
Which brings me to the next point. Even though I intend to maintain the document, don't expect me to do much in the near future. I've been working on it for far too long now and need a break. Integrating all the editing Jonathan produced plus today's line breaking have given me the rest. I haven't even integrated all the comments I've received. I know the structure of the document is in a few places a bit weak, esp section 5 which contains a lot of non-NUMA information. But it was simply too much work so far. Maybe some day.
