title: Python Multiprocessing - shared memory
body: <ol>
  <li>From the main process, I create 3 child processes and I pass an instance of a 'common' class...the same instance is passed to all 3 child processes. </li>
  <li>This common class has a dictionary and a queue (which contains a lot of items)</li>
  <li>These child processes retrieve 'items' from this queue</li>
  <li>For these items, I call a REST service to get some data about the 'item'</li>
  <li>I add this info to the "common" dictionary</li>
  <li>There are no errors</li>
  </ol>
  
  <p>However, when I try to access this dictionary from the main process, its empty.</p>
