title: Closing all threads with a keyboard interrupt
body: <p>What I'm trying to do here is use a keyboard interrupt to exit all ongoing threads in the program. This is a pared down version of my code where the thread is created:</p>
  
  <pre><code>for i in taskDictionary:
      try:
          sleep(60)
          thread = Thread(target = mainModule.executeThread)
          thread.start()
      except KeyboardInterrupt:
          thread.__stop()
  </code></pre>
  
  <p>The program itself is far more complicated, accounting for tons of different variables that affect the threads and even having the option to launch in a sequential mode, where tasks are not threaded, but instead launched one-by-one so there might be some problems with this small variation I just conjured up.
  I have done this in ways that produced 50/50 results. The interrupts would work but the threads would never cleanly exit. Sometimes they would keep going but halt the execution of future threads, some times they would exit with a massive error regarding the interrupt, other times the interrupts would do nothing at all. Last time I ran this the program stopped any future threads from executing but did not stop the current thread.
  Is there any way to exit the threads without going into the module the thread is actually executing in?</p>
