Did He really need 2 posts and all that test time?

for(var 
 nullable = null,
 i = 0,
 loop = 500000,
 timeOut = setTimeout(function(){alert(nullable)}, 1);
 i < loop; i++
) {
 if(i + 1 === loop)
  nullable = "Hello World";
};

Sometime I really don't understand Ajaxian choice ... they totally ignored my JSTONE experiment but they spent time to post about a normal JS behaviour :-(
