[Mpi3-hybridpm] Better Forum INIT/FINALIZE slides

[Pavan Balaji]

Jeff,

Some comments --

1. Slide 2: The main goals need to be rephrased.  The goals are to 
overcome limitations while using MPI in stacked and threaded libraries. 
  For stacked libraries, the single INIT/FINALIZE limitation requires 
each library to have global knowledge on who else is using MPI.  For 
threaded libraries, there are race conditions.

2. Slide 5: Sorry, I missed this earlier.  I'm not in favor of changing 
the current definitions of IS_INITIALIZED and IS_FINALIZED.  Better to 
deprecate them and add MPI_IS_WITHIN_EPOCH.

3. Slide 10: I don't think we agreed that the requested level will be 
ignored by subsequent calls.  That's a quality of implementation issue.

4. Slide 15: We can say that our current stand is to remove that 
restriction that the "main thread" needs to finalize.

Btw, I've requested for plenary time.
