[OMPI users] Disabling barrier in MPI_Finalize

[Mccall, Kurt E. (MSFC-EV41) via users]

Hi,

If a single process needs to exit, MPI_Finalize will pause at a barrier, 
possibly waiting for pending communications to complete.  Does OpenMPI have any 
means to disable this behavior, so the a single process can exit normally if 
the application calls for it?

Thanks,
Kurt
