    Problem Summary Tests assume that an action performed by a transport endpoint is
    synchronously visible to the peer endpoint.
    Problem Text The problem with these tests is that they assume that an action
    performed by a transport endpoint is synchronously visible to the peer
    endpoint, as soon as the system call that performed the action returned.

    In this test the essential sequence is:

    0. client asks the server to close the connection using local IPC
    mechanism.
    1. server closes the established connection using close()
    2. server signals the client using local IPC mechanism
    3. client sends some data using send()
    4. client sends some more data using send()

    client expects 4. to fail with SIGPIPE.

    Both the endpoints are local to a machine. 1. detaches the association
    between the stream and the connection. Any subsequent incoming data for
    the server will elicit a TCP RST. This data is generated by step 3.
    Step 3. elicits an RST from the server and the connection
    enters the closed state at the server. When this RST is received by the
    transport at the client, the client endpoint will also enter the closed
    state. However there is no synchronization between the exact time at
    which the RST is received and processed by the client and step 4. Though
    in this case both the transport end points are local to a machine, in
    the general case the RST has to travel over the wire and there is no way
    to determine whether the incoming RST from the server happens earlier
    or whether step 4 happens earlier. Neither TCP nor the Single Unix Spec
    make any distinction between TCP connections local to a machine or
    whether they go over the wire.
