title: How can stop the browser from trying to render the page until my javascript function is complete?
body: <p>I want to be able to do this:</p>
  
  <p>1: Wait till DOM is loaded<br>
  2: Tell the browser not to render the page yet<br>
  3: Perform manipulation of DOM with a javascript library of choice (I'm using dojo)<br>
  4: Tell the browser it can now render the page  </p>
  
  <p>Otherwise, the user sees the intial DOM state briefly before it's manipulated. It's gross.</p>
  
  <p>Thanks!</p>
