MPI_Comm_shm_alloc probably needs an Advice to Users about the input communicator argument to this function. Just passing any communicator (e.g. MPI_COMM_WORLD) may not result in successful shared memory allocation. One use case is the communicator should represent processes on the same node. Other use cases could be implementation defined. Not sure of the exact language to put here, but it would be useful to make users aware of this issue in some way, rather than say nothing at all.

This proposal is a shrunk version of earlier proposals, with only helper threads and shared memory allocation functions included. Endpoints are not included. Is the endpoints proposal going to be put forth separately later? I hope it is in good shape because it was a promising idea.
