title: Python IDLE freezes
body: <p>This is absolutely frustrating, but I am not sure if the following is an issue only on my machine or with IDLE in general.</p>
  
  <p>When attempting to print a long list in the shell, and that could happen by accident while debugging, the program crushes and you have to restart it manually.</p>
  
  <p>Even worse, if you have a few editor windows open, it always spawns a few sub-processes, and each of these has to be manually shut down from the task manager.</p>
  
  <p>Is there any way to avoid that?</p>
  
  <p>I am using Python 3, by the way.</p>
