In our test run sections we set the "timeout" param, e.g.,

  timeout = &max(60, &multiply(20, &test_np()))

That would set the timeout for the test run section to the maximum of
60 seconds and 20 * np seconds.

MTT will kill the orterun after the timeout, but we've been seeing
zombie a.out's clog up our cluster. You might want to stick this in
your "MPI details" section:

  after_all_exec = mpirun @hosts@ orte-clean -v

Assuming orte-clean still works.
