Technically, Windows is POSIX compliant. You have to turn off a bunch of 
features, turn on another bunch of features, and what you get is the bare 
minimum POSIX compliance possible, but it's enough to tick the check box 
for POSIX compliance.

What what of it? POSIX is not a minimum set of requirements for Python. 
POSIX is a set of standards that describes how Linux/Unix/MacOS systems 
are expected to behave. Adhering to the POSIX standard isn't a 
requirement for Python.

To paraphrase Isaac Asimov, "People who say the earth is flat are wrong, 
and people who say the earth is a sphere are wrong, but if you say that 
those two groups of people are equally wrong, you are more wrong than 
both of them put together."
