    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.

    That's really great, it's a shame this patch didn't get much interest. Do you feel like adding test to this, it would probably psuh for its inclusion ?

    Bump. This functionality seems to be needed if anyone is going to be
    messing around with advanced features of IPv6. As it stands, the socket
    module in Python 2.6/3.0 is incomplete without this.

    Just a followup comment to note that adding support for
    sendmsg()/recvmsg() is what you need to do "file descriptor passing"
    between processes on Unix---another technique for writing network servers.

    The patch doesn't apply cleanly to the current trunk (which is
    understandable, given the patch is from 2005). Also, some tests would be
    welcome as Thomas said. And bonus points for documentation :)
