 *    - Add WSACancel* and correct handle management. (works rather well for
 *      now without it.)
 *    - Verify & Check all calls for correctness
 *      (currently only WSAGetHostByName*, WSAGetServByPort* calls)
 *    - Check error returns.
 *    - mirc/mirc32 Finger @linux.kernel.org sometimes fails in threaded mode.
 *      (not sure why)
 *    - This implementation did ignore the "NOTE:" section above (since the
 *      whole stuff did not work anyway to other changes).
