This sample contains a potential deadlock. The communication pattern is as follows:
Process 0 Process 1
MPI_Buffer_attach()
MPI_Bsend()
MPI_Buffer_detach()
MPI_Barrier() MPI_Barrier()
MPI_Recv()
MPI_Buffer_detach() will block until the message is
transferred into the network. There is no guarantee that
this is possible because the recipient is not entering
its MPI_Recv() until barrier occurs.
