title: How to free memory with python garbage collection with list
body: <p>I have a python process with a loop :</p>
  
  <pre><code>for i in range(1, 100000) :
      vv = get_biglist( 10000 )
      ....
  </code></pre>
  
  <p>For some reasons, interpreter memory
  keeps increasing.</p>
  
  <p>Is there a way to contain memory size or to free
  memory to the OS ?</p>
