The issue of whether the new communicator is called COMM_EWORLD or
COMM_WORLD has probably been debated in the working group phone calls,
but I think large applications would want to incrementally add hybrid
features to their code, and for them it would be cleaner to have a
separate COMM_EWORLD that affects only the part of the code they are
messing with. The rest of the code that already makes explicit
references to COMM_WORLD remains unchanged. If we were designing MPI
from scratch, however, it would make sense to include all endpoints in
COMM_WORLD.
