[Mpi-22] [MPI Forum] #109: Nonblocking Collective Operations

[William Gropp]

Here's my suggestion:

The draft is intended to alert people to very likely additions and  
even changes to the MPI standard.  The draft should be in as good a  
shape as possible, so fixes like this to the text are reasonable.

However, these are significant enough that for the Standard (not the  
draft), we'll clearly need another vote.  We should postpone that vote  
until we're closer to issuing an official standard, since other things  
may change (for example, C++  or Fortran 200x bindings).
