Is there some test we can do to check whether ch3:sock is being used so that we can choose a safe algorithm?

A run-time test that doesn't require looking at which symbols are compiled into the app? I can't think of one off the top of my head, although I suppose we could add one in the future via either MPI_T or the new MPI_Get_library_version routine.

I think that MPI_Get_library_version is the most sensible way to do it. There's some precedent for this to return a lot of information: http://blogs.cisco.com/performance/mpi-3-small-new-function-mpi_get_library_....
