I don't think that we're that far ahead on this but my personal 
opinion is that we should not add new sets of MPI calls unless it is 
truly necessary. I think that in this case we can get all the 
functionality we need by adding
- a new function that the user would call at initialization time to 
set the error detection/notification policy and
- communicating error events via new return values and error handler calls.
