    otherwise StateSaveDir (which is likely a shared directory, possibly
    making core file identification more difficult).

    Note that the required node list is set to every node used when
    a job is started via sched/wiki2.

    tests, patch.1.2.0-pre11.070111.plane from Dan Palermo (HP).

    Communications now supported directly between appliciation tasks via
    Slurm's PMI library. Srun sends single message to one task on each node
    and that forwards key-pairs to other tasks on that nodes. Old code send
    key-pairs directly to each task.
    NOTE: PMI applications must re-link with this new library.

BLUEGENE - modifications to allow sinfo and sview (in partition mode) view the correct used nodes and nodes in an error state on a bluegene system.

BLUEGENE - added logic to be able to reboot a block on the start of a job based on the input from srun.
