27  *      - Verify & Check all calls for correctness
28  *        (currently only WSAGetHostByName*, WSAGetServByPort* calls)
29  *      - Check error returns.
30  *      - mirc/mirc32 Finger @linux.kernel.org sometimes fails in threaded mode.
31  *        (not sure why)
32  *      - This implementation did ignore the "NOTE:" section above (since the
