title: Why don't synchronous ajax calls in jquery support timeout?
body: <p>I was reading <a href="http://forum.jquery.com/topic/ajax-timeout-not-working" rel="nofollow">here</a> that synchronous ajax calls in jquery don't time out. </p>
  
  <p>Is this a technical limitation, or just something the authors didn't feel like supporting? What actually happens under the table when an ajax call is synchronous?</p>
