title: Can I use QTimer to implement a multthreaded algorithm?
body: <p>currently I need to implement a multi-threaded algorithm based on Qt. Maybe I should try to extend <code>QThread</code>. 
  But before that, I'd like to ask, if I can just use two <code>QTimer</code>s <code>timer1</code>, <code>timer2</code>, and connect their timeout signal to the threads respectively, to implement a "fake" multi-threaded program?</p>
