    Problem Summary PIN4U.00001 Peer is shut down for reading condition should not be tested.
    Problem Text
    The original spec indicates that an EPIPE error should be
    returned when a socket is shutdown for writing, or when it is
    connection-oriented and the peer is closed or shut down for
    reading. In existing practice some implementations do not raise
    this error when the peer is shut down for reading, but do when it
    is closed.

    A resolution resolved this as an error and stated the text for
    all send*() interfaces should be changed to read

    "...or the socket is connection-oriented and is no longer connected."

    The test should be changed to reflect this resolution.
