Standards/RFCs/etc are very nice piece of papers, reality tends to be less
forgiven: a program/routine will always do what the programmer intended,
now the problem is defining 'what the programmer intended' :-)

the advantage of open source is that you can check what the real world does,
and sometimes it reflects the wishes of the docs/posix/rfc, but mostly
it reflects the programmer interpretation.
