(changed the subjet to be more accurate)

I notice that ticket #5 has already had a 1st reading; it will  
certainly change the ABI.

My point: if we are taking a hard line to make it possible for any  
existing MPI-2.1 application to be able to run against MPI-2.1 and  
MPI-2.2 versions of the same implementation, we will need to review  
all MPI-2.2 tickets.
