Mike, I have not meant covering for some possible old versions, but covering
for future versions; if you know which version the man-page documents, you can
decide if you need to check further to see if your version has something new
there.

I don't know who was the original author describing O_NONBLOCK. I have never
really tended to misinterpret this myself, "Many  file  systems and disks were
considered to be fast enough that the implementation of O_NONBLOCK was deemed
unnecessary.  So, O_NONBLOCK may not be available on files and/or disks" seemed
always rather clear to me, but I agree more detail and mentioning this at other
places than read(2) documentation as well would do good.
