Please David just revert 0856a304091b33a8e

Done.

Eric,

Can you re-spin a patch that incorporates your idea that we don't
add pid/credential references when we are not requesting credentials
in the socket. And probably another one that remove unnecessary
pid/credentials references in send/receive when we do use credentials?

Sure, I did it this morning, please review it if you have some time.

If we find a regression (some popular app doing write() and expecting
credential to be sent to receiver), we could test the SOCK_PASSCRED flag
on receiver socket.
