Ergo, it would be good to respawn the daemons before every testsuite. Some tests might also involve killing a FTB daemon (ftb_agent) while a test is being run to test the fault-tolerant routing in the network. The ft/correctness examples in the ompi-tests/ are really a good way to start. You'd also want a wrapper similar to run-cr-correctness.pl to maybe check if the tests have passed successfully or not.
