title: PyCharm - how to suspend all threads
body: <p>We're using PyCharm 5.0.1 for multi-thread debugging. <br/>
  When it stops at a break point, only the specific thread stops while all the other continue. This makes it hard to "freeze the moment" and check params values, and the current state of the other threads.<br/><br/>
  Is it possible to suspend all the thread while one of them has stopped on a breakpoint?</p>
  
  <p>Is this possible on the newest Pycharm 2016 or the [latest] Pycharm version?</p>
