 We declare that all endpoints must be "progressed" whenever any
 communication is done. This way, the implementation can use whatever
 endpoints internally to perform the communications. It does require that
 there be some new interface by which an endpoint may make progress without
 having explicit requests.

 Since the overall "endpoints" proposal is a departure/extension of the
 MPI2 "single endpoint" model, it may be reasonable to attach these
 additional requirements on programs that wish to use multiple endpoints.
