        // We can only depend on the accepted address if multi-shot is not used.
        // From the manpage:
        //       The multishot variants allow an application to issue a single
        //       accept request, which will repeatedly trigger a CQE when a
        //       connection request comes in. Like other multishot type requests,
        //       the application should look at the CQE flags and see if
        //       IORING_CQE_F_MORE is set on completion as an indication of whether
        //       or not the accept request will generate further CQEs. Note that
        //       for the multishot variants, setting addr and addrlen may not make
        //       a lot of sense, as the same value would be used for every accepted
        //       connection. This means that the data written to addr may be
        //       overwritten by a new connection before the application has had
        //       time to process a past connection. If the application knows that a
        //       new connection cannot come in before a previous one has been
        //       processed, it may be used as expected.
