Nice scarecrow.

Linux has and will break POSIX where POSIX asks unreasonable and
stupid things.

And in particular we will not follow POSIX if doing so breaks
pervasive practices in userspace that have worked under Linux for a
long time.

We do not follow paper standards blindly.  Practical considerations
alway trump standards.  Standards are often wrong or it's authors did
not consider a particular case sufficiently.
