No, I did not.

He didn't.

Counting the number of occurrences of some words without considering their
context is a meaningless metric.

1. When was the last time you, or anyone you know, bought or saw anyone
   using a computer or other gadget that wasn't either Apple, Windows, or
   some flavor of Unix?

2. How would you develop an OS without the concept of a PID? (No, the sucky
   iPhone "OS" doesn't count, since it DOESN'T MULTITASK. :P)

3. Does anyone tend to make OSen (iPhone "OS" again does not count) that
   *aren't* fairly POSIXy anymore?

4. And before you bring up some obscure legacy OS on some archaic mainframe
   that some large banking institution in some obscure corner of the world
   is still using to run some old bit of business logic for which they've
   long since lost all the source code, recall that the context here is
   *development of some new software*. Nobody sane develops *new* software
   for clunkers like that -- they develop it for their farm of Unix servers
   or their ten thousand cubicle boxen running Windows, even if maybe it
   uses some network to get some service from the legacy mainframe.

It's starting to look like you don't either, which naturally causes one to
question why you bother writing them.
