Yes, but we rely on an internal info key as well in order to avoid the search time. Though I think we can optimize this search with an AVL tree or something.
Note that Jeff’s ticket gives more capability that this — it allows the user to do load/store accesses. Your info key only allows the MPI implementation to internally optimize communication.
