+     * The reason is because application may need to distinguish

+     *  a) sockaddr is not initialized. This is by convention
+     *     indicated by sa_family==0.
+     *  b) sockaddr is initialized with zero address. This is
+     *     indicated with the address field having zero address.
+     *  c) sockaddr is initialized with valid address/port.
+     *
+     * If we enable this assertion, then application will loose
+     * the capability to specify condition a), since it will be
+     * forced to always initialize sockaddr (even with zero address).
+     * This may break some parts of upper layer libraries.
