title: psutil without C extensions
body: <p>I'm considering using <em>psutil</em> for CPU and Volumes monitoring. However, for my project it would be ideal if I could somehow get rid of the C extensions <em>psutil</em> uses:</p>
  
  <ul>
  <li>I want my project to be as self-contained as possible with no need for compilation on client side.</li>
  </ul>
  
  <p>Is this possible? Or is there and earlier pure-python version of <em>psutil</em> I can use?</p>
