Hmm, that turns out to be the point. I've checked and it is not
in '/usr/local/lib/perl5/5.8.8/mach/Socket.pm'.

I think my understanding if when I originally posted the email was
wrong as well. I need to set the socket option LOCAL_CREDS and fetch
them using recvmsg.

Can some one please verify my understanding of this is right?
