  24  * FIXME:
  25  *      - Add WSACancel* and correct handle management. (works rather well for
  26  *        now without it.)
  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
  33  *        whole stuff did not work anyway to other changes).
