The Collective WG would like to read issue 78 (PR 48), Non-blocking
communicator/file/win constructors/destructors/etc, respectively to "Groups, Contexts, Communicators, Caching," "Topology," and "I/O" chapters. We are pursuing the broadest possible support of completely
nonblocking MPI programs and "orthogonalizing the design"
of MPI-Next.
Correlated tickets will also be read in concert with this ticket (#81, #82).
