title: "Asyncio Event Loop is Closed" when getting loop
body: <p>When trying to run the asyncio hello world code example given in the docs:</p>
  
  <pre><code>import asyncio
  
  async def hello_world():
      print("Hello World!")
  
  loop = asyncio.get_event_loop()
  # Blocking call which returns when the hello_world() coroutine is done
  loop.run_until_complete(hello_world())
  loop.close()
  </code></pre>
  
  <p>I get the error: </p>
  
  <pre><code>RuntimeError: Event loop is closed
  </code></pre>
  
  <p>I am using python 3.5.3.</p>
