title: Real-time output from engines in IPython parallel?
body: <p>I am running a bunch of long-running tasks with IPython's great <a href="http://ipython.org/ipython-doc/dev/parallel/" rel="nofollow">parallelization</a> functionality. </p>
  
  <p>How can I get real-time output from the ipengines' stdout in my IPython client?</p>
  
  <p>E.g., I'm running <code>dview.map_async(fun, lots_of_args)</code> and <code>fun</code> prints to stdout. I would like to see the outputs as they are happening.</p>
  
  <p>I know about <code>AsyncResult.display_output()</code>, but it's only available <em>after</em> all tasks have finished.</p>
