Comment 7 for bug 1490043

The fact that kill doesn't return anything on stderr is puzzling...I wish we would have used os.kill instead of shelling out to invoke kill.

Having said that, I wonder if a better way to simulate the situation you want to test here is to signal -9 without using process.disable.

 We could do after checking that signal 0 has returned positively. That is ultimately the green flag that you can simulate the process crash.
