    Passing --ifhn here means that the slave nodes will try to listen on the master node's
IP address. If multi-interface functionality is made available for slave nodes, it needs to
be specified in a way separate from the way it's specified for the master node. Otherwise,
MPI will fail to run on slave nodes.

to statusUpdate() so that it stops when all tasks have been finished, which occurs when the
executor's launched mpd processes have all exited.

termination...I think. cleanup() still terminates all mpd's in the slave, but shutdown doesn't.
