title: Opening QtApplication from python process that is forked from QtThread
body: <p>I have a server-client architecture. The server is a <code>QtApplication</code> and contains a <code>QThread</code>. </p>
  
  <p>I am trying to open a new client process using python's built in <code>multiprocessing</code>, from the QThread, and from that new proccess, open a new <code>QtApplication</code> . Such that the server and the client are both running QtApplications</p>
  
  <p>The problem is that I am getting the following error:</p>
  
  <blockquote>
    <p>WARNING: QApplication was not created in the main() thread.</p>
  </blockquote>
  
  <p>The QApplication is being created in the main thread of the new processes, so I am not sure why this error is occurring.</p>
