    Fixing an unexpected issue during test interrupts
    
    When we get a KeyboardInterrupt (ie, the user presses ctrl+c) we sometimes
    don't have a tor process to kill which results in an unexpected stacktrace.
    I'm not quite sure why, but if a process doesn't exist then... well... guess
    we don't need to kill it.
