title: My Python interactive mode uses more and more memory
body: <p>I'm using Windows 7 64 bit and Python 3.7.1 (Anaconda) takes more and more memory after each execution to grab the interactive mode.</p>
  
  <h2>Symptoms</h2>
  
  <p>If I execute the following line : </p>
  
  <pre><code>&gt; python -c "print('ok')"
  </code></pre>
  
  <p>It will run without any problems almost immediately.</p>
  
  <p>Now if I run python directly :</p>
  
  <pre><code>&gt; python
  </code></pre>
  
  <p>It first display the following : </p>
  
  <pre><code>Python 3.7.1 (default, Oct 28 2018, 08:39:03) [MSC v.1912 64 bit (AMD64)] :: Anaconda custom (64-bit) on win32
  Type "help", "copyright", "credits" or "license" for more information.
  </code></pre>
  
  <p>And then start to load...</p>
  
  <p>First time I noticed that python was more and more slow to access the interactive mode he needed already few seconds. Now, it can be at least 2 minutes to execute :/ and it is using more and more memory > 3.0 Go ! </p>
  
  <p>I did some search but didn't find anything about that problem. Does someone has an idea on how I could figure out what's going on ? </p>
  
  <h2>Edit</h2>
  
  <p>I was able to get the interactive mode at once by doing </p>
  
  <pre><code>&gt; python -S 
  </code></pre>
