title: Using ActionController::Live is sleep required?
body: <p>I followed the <a href="http://api.rubyonrails.org/classes/ActionController/Live.html" rel="nofollow">Rails reference</a> to stream some data to the client.</p>
  
  <p>Is the Sleep necessary since I have seen the usage of Sleep everywhere? Does Rails internally use Sleep in Live to stream data?</p>
