I assume that most MPI implementations will have the values be equal  
just by how their f2c/c2f engines work (OMPI will).  I was just  
wondering if it's necessary to *mandate* that behavior.

Do apps really check handle equality?  If so, I agree that anything  
other than path A violates the law of least astonishment.  I assumed  
that not many apps do this, but I probably don't have a good basis for  
reference.
