  19  * ---- rpcss_main.c:
  20  *   Initialize and start serving requests.  Bail if rpcss already is
  21  *   running.
  22  *
  23  * ---- RPCSS.EXE:
  24  *
  25  *   Wine needs a server whose role is somewhat like that
  26  *   of rpcss.exe in windows.  This is not a clone of
  27  *   windows rpcss at all.  It has been given the same name, however,
  28  *   to provide for the possibility that at some point in the future,
  29  *   it may become interface compatible with the "real" rpcss.exe on
  30  *   Windows.
  31  *
  32  * ---- KNOWN BUGS / TODO:
  33  *
  34  *   o Service hooks are unimplemented (if you bother to implement
  35  *     these, also implement net.exe, at least for "net start" and
  36  *     "net stop" (should be pretty easy I guess, assuming the rest
  37  *     of the services API infrastructure works.
  38  *
  39  *   o There is a looming problem regarding listening on privileged
  40  *     ports.  We will need to be able to coexist with SAMBA, and be able
  41  *     to function without running winelib code as root.  This may
  42  *     take some doing, including significant reconceptualization of the
  43  *     role of rpcss.exe in wine.
