[Node manager] exception handler should not kill parent process
A race condition in test_fatal_error (tests.test_failure.ActorUnhandledExceptionTest) causes os.killpg() to be called after it has been unstubbed. This kills the test suite and run-tests.sh.There are two problems here:
- The test should not have a race condition
- The exception handler should only kill node manager itself, not other processes.
Proposed fix for overkill¶
Use os._exit() or os.kill(0,9) instead of os.killpg()
Proposed fix for test race¶

The test race might still exist. However, it hasn't been seen recently, so maybe some other changes have fixed it by accident.
(11:07:12) tetron_: I haven't seen the race condition happen (11:07:59) tetron_: and I haven't been able to work out a sequence that would cause it to happen (11:10:51) tetron_: I believe the race only happens if the test also fails for some other reason and it's unable to wait for the actor to stop
