    Problem Text
    The test attempts to generate a TLOOK error from t_listen(). To do this,
    the slave system sends a connect request followed immediately by a
    disconnect. In the implementation being tested, the connect and disconnect
    indication are queued at the peer transport provider, so that the master
    program receives the both the T_LISTEN and T_DISCONNECT events. The
    test fails because it expects only the T_DISCONNECT event to be received.

    There is no requirement that an XTI implementation delete a T_LISTEN
    event when a T_DISCONNECT event occurs. In fact this could be very
    difficult to implement, as an endpoint could have several listen events
    queued for outstanding connections at the time a disconnect occurs, so
    it would have to search the entire queue for the matching T_LISTEN event
    to be destroyed. It seems reasonable to allow the T_LISTEN event to
    occur in this case, as long as it is followed by a T_DISCONNECT event,
    as shown in the trace below.

    A better test of the TLOOK error from t_listen() would be to have the
    slave program delay before calling t_snddis(), and have the master test
    program call t_listen() twice, so that the T_DISCONNECT event would
    always be indicated by a TLOOK error received on the second t_listen().
