The fact that application proc called Abort (read failed) doesn't
mean that ORTE subsystem has failed - vice versa it does it's work
to gracefuly exit the whole application.
orted exiting with non-zero status creates a problem for at least
plm/slurm environments where orteds are launched via `srun` with
"--kill-on-bad-exit" flag. If one of orteds has exited with non-
zero status slurm will immediately kill all other orteds. As the
result we see a lot of leftover in the `/tmp` directory.
