The following tar.bz2 contains a feature enhancement
proposal for the socket module to create wrappings of
the recvmsg and sendmsg primitives. These are sometimes
useful, especially when dealing with ancillary
messages, such as communicating the process, user and
group id of a remote process to a server for proper
identification.

These functions have so far been available in a
separate module (python-eunuchs from the twisted
project), but as they are standard POSIX and have been
available on *BSD, AIX, Linux and several other OSs for
some time they should be integrated into the core
socket module.

The attached file contains patches for configure.in the
socket module, socket.py and pyconfig.h.in. I've yet to
write a test-suite, and the documentation could use
some reworking.
