            # appears to be an implementation choice (see
            # inet_accept in inet/ipv4/af_inet.c).  On macOS X,
            # such a listener is not considered readable, so
            # accept(2) will never be called.  Calling accept(2) on
            # such a listener, however, does not return at all.
