Something simple for testing slow loading pages

ba-block.js

// Block page loading, for testing ready events / etc.

function block( delay ) {
  var html = '<script src="http://1.cuzillion.com/bin/resource.cgi?type=js&sleep='
    + delay + '&jsdelay=' + delay + '&t=' + +new Date + '"><\/script>';
  
  document.write( html );
};

/*

Sample usage. Block page loading for 1 second:
<script type="text/javascript">block(1);</script>

*/
