Hi All,

In reviewing the proposal, a couple questions/comments came up:

(1) Are the semantics for the MPI probe operations (probe, iprobe, mprobe)
well defined?  Including when MPI_ANY_SOURCE is used?

(2) For comm_shrink, what happens when the remote group in an
intercommunicator becomes empty?  Is it valid to get back an
intercommunicator with an empty remote group?

(3) In 15.2 (pg. 594:21), can we replace the sentence "always complete in a
finite amount of time" with the simpler "eventually complete"?
