If you're exiting the process, you won't cause any kind of problems --
the OS will clean up everything.
However, we might also have the orted clean up some things when MPI
processes unexpectedly die (e.g., filesystem temporary files in /
tmp). So you might want to leave those around to clean themselves up
and die naturally.
