Just to make sure we are speaking the same language, here is what the
Oxford English Dictionary sez
Design: (1) a plan or scheme conceived in the mind; a project.
(2) a purpose, an intention, an aim
(3) an end in view, a goal
(4) A preliminary sketch, a plan or pattern

For the verb we get things like: "draw, sketch, outline, delineate"

You're on. Send me the $5.
Here's what Dennis Ritchie wrote in his preface to the re-issued Lions
"you will see in the code an underlying structure that has
lasted a long time and has managed to accomodate vast changes
in the computing environment"

You appear to be using "design" to mean "complete specification".
See above.

Memory fades with age, as I know from sad experience, but try to
remember who wrote things like:

|However, I still would not call "pthreads" designed.
|Engineered. Even well done for what it tried to do. But not "Designed".
|This is like VMS. It was good, solid, engineering. Design? Who needs
|design? It _worked_.
|But that's not how UNIX is or should be. There was more than just
|engineering in UNIX. There was Design with a capital "D". Notions of
|"process" vs "file", and things that transcend pure engineering.
|In the end, it comes down to aesthetics. pthreads is "let's solve a
|problem". But it's not answering the big questions in the universe.
|It's not asking itself "what is the underlying _meaning_ of threads?".
|"What is the big picture?".

Some academic twit, no doubt, with no understanding or experience in
actually making a blue collar OS really work.

Please send the $5 soon.
