title: Stopping a Fabric Task From Running
body: <p>The method I currently use if one fabric task fails on one of my servers is </p>
  
  <p>to</p>
  
  <pre><code>try:
     sudo(...)
  except SystemExit():
     raise Exception("You should fix this with...")
  </code></pre>
  
  <p>However, this leaves an unpleasant stack trace from the exception when all I want to do is print the message from the exception. However, if I don't throw this exception then the fabric script will continue to run on my other servers when I want it to stop.</p>
  
  <p>Is there a way to stop all fabric tasks?</p>
