This works for "reading" state, but has no way to set a processes state. (Not sure how radical your trying to go here... is part of the change here that there would no longer be a MPI_PROC_STATE_NULL state?)

MPI_GET_PROC_STATE_NEW(state_handle1, state_handle2, state_handle_new) IN: MPI_PROC_STATE state_handle1 IN: MPI_PROC_STATE state_handle2 OUT: MPI_PROC_STATE state_handle_new This gives newly failed processes in state_handle2 since state_handle1.
