[mpi-21] MPI_FINALIZE

[Rolf Rabenseifner]

Mainly to Jeff Squyres, Hubert Ritzdorf, Rolf Rabenseifner, Nicholas Nevin,
          Bill Gropp, Dick Treumann 

This is a follow up to:
  MPI_FINALIZE in MPI-2 (with spawn) 
  in http://www.cs.uiuc.edu/homes/wgropp/projects/parallel/MPI/mpi-errata/index.html
with mail discussion in
  http://www.cs.uiuc.edu/homes/wgropp/projects/parallel/MPI/mpi-errata/discuss/finalize/
_________________________________________

When I understand correctly, then a clarification is not needed
because the MPI standard expresses all, i.e.
- MPI_Finalize need not to behave like a barrier 
- but is allowed to have a barrier inside.
- If the user wants to exit one spawned process while
  the others still continue to work, he/she must
  disconnect this process before calling MPI_Finalize on it.

If somebody wants a clarification to be included into the standard
and therefore in Ballot 4, please send me your wording
with the page and line references included.

If all agree, that no clarification is needed, then I would finish 
this track.

Best regards
Rolf
