Not quite that simple, Patrick. Think of things like MPI_Sendrecv, where the "send" call is below that of the user's code.
You have a point, Ralph. Although, that would be 8 more lines to add to the user MPI code to define a MPI_Sendrecv macro :-)
Seriously, this particular proposal is not the most flaming example of OpenMPI doing too much or going too far. I personally thought that the discussion about affinity was much more revealing in itself, like the part about in effect replacing the OS scheduler.
