Hi Folks,

Here's the list of mpi opaque objects and a few additional constructs for
consideration of states in the presence of process failures:

communicators - Aourelian, Wesley
groups -  Rich G.
data types - Sayantan
RMA windows - Howard
files (file handles) - Darius B.
info object  - Darius
error handler - Darius
message obj. - David S.
request - Manjo
status - Manjo
op  - Darius
port (mpi-2 dynamic) - David S.
user buffers attached to MPI for bsends - Sayantan

Need to define lifecycle of the object in the case of no process failures,
and in the case when one or more process failures occur while the
object exists.
