The idea would be to hardwire support for MPI_THREAD_MULTIPLE to be off,
just as we have done for progress threads. Threads might still be used
for other purposes -- e.g., ORTE, openib async thread, etc.

>>>We wanted to clean up MPI_THREAD_MULTIPLE support in the trunk and port these changes back to 1.5.x, but it's unclear to me what our expectations should be about any MPI_THREAD_MULTIPLE test succeeding. How do we assess (test) our changes? Or, should we just hardwire thread support to be off, as we have done with progress threads?
