[Mpi3-ft] Asynchronous Process Management Interface Proposal

[Josh Hursey]

I just posed a first draft of an Asynchronous interface to the  
MPI_Comm_spawn operations for process management. The wiki page is here:
  http://svn.mpi-forum.org/trac/mpi-forum-web/wiki/Async-proc-mgmt

This is a rough draft at the moment, and I know we have not talked  
about this on the teleconference calls yet. I wanted to post something  
so we can start talking about it at a high level before nailing down  
too many specifics. And to see if there is anyone interested in  
helping me with this proposal.

Let me know what you think.

Cheers,
Josh
