title: Google Maps JSv3 Freezes for a few seconds every 30 seconds
body: <p>As per title, does anyone know why it freezes every 30 seconds? 
  I figured that it was some sort of timer with Google Maps but cant find any such reference. </p>
  
  <p>To recreate, simply copy into a local file the full html + javascript from:</p>
  
  <p><a href="https://developers.google.com/maps/documentation/javascript/examples/map-simple" rel="nofollow">https://developers.google.com/maps/documentation/javascript/examples/map-simple</a> </p>
  
  <p>Open the local html file and then just move the map around and it will freeze within 30 seconds. Once it unfreezes, it works fine until 30 seconds have elapsed.</p>
  
  <p>Seems to only happen in IE (i used version 11). Note that it doesnt freeze within the Google example page above.</p>
  
  <p>Any help would be appreciated.</p>
