I think we really need to have in the very short term some solution at 
hand which effectively allows for both the cma being used and the local 
SA not replicating the SA.

This is since the trunk is used in various environments, currently most 
of them are not "all-to-all MPI doing path query" and the SA replica is 
not mature/tested enough to prove that any SM/SA can live more or less 
happily with it.

Does it makes sense to you? can it be added with high priority?

Or.
