[Mpi3-ft] MPI Process Management Proposal - Updated

[Josh Hursey]

I just updated the Process Management proposal in the wiki:
  http://svn.mpi-forum.org/trac/mpi-forum-web/wiki/Async-proc-mgmt

This contains discussion of the non-blocking process management  
interfaces. It also moved the discussion of connect/accept extensions  
from the FT Mgr/worker proposal to this one for consolidation  
purposes. I put a note in the FT Mgr/Worker proposal indicating this  
transition, but did not remove any of the original text from it so we  
can have it as a reference.

This should be regarded as a rough draft still as I made no actual  
attempt at writing precise standardize language, but opted for a more  
casual presentation so we can more freely discuss the high level  
merits of the proposal.

Sorry for the delay on this. I was hoping to finish it earlier to  
allow more time for review before the teleconf.

Cheers,
Josh
