    Problem Summary PIN4U.00072 This IR claims that historical listen() behavior should be allowed in UNIX98
    Problem Text
    Note that we calculate the true qlimit with the following formula:
    The system actually enforces the limit of pending connections as
    ((3 * backlog) / 2) + 1

    We did the right thing by converting a negative backlog value to 0. Then
    the qlimit will be 1 based on the formula. That was why the connect call
    succeeded.

    One problem here: with this formula and we convert all negative value to 0,
    we can not create a situation of qlimit of 0. We believe that the
    test should not require that the connect call not succeed in this
    case.

    Review Response
    This request concerns the same issue as PIN4U.00046.

    Although the wording of the specification changed slightly between
    XNS4 and XNS5, the same grey area still exists in XNS5, and so a new
    PIN should be issued that can be referenced in UNIX98 registrations.

    It is recommended that a permanent interpretation is granted.
