Description

If you have an XMLHttpRequest object, and you want to recive data synchronous it will not work.
Example:
var aVar = 'some text';
request = new XMLHttpRequest;
request.open('GET', 'http://localhost/someurl.js', false);
request.onreadystatechange = function() {
   if (request.readyState == 4) {
       aVar = request.responseText;
       return;
}
request.send(null);
alert(aVar);//it will alert 'some text' instead of the value of request.responseText

I've tested with IE5.5/6 Opera 8.54 and works fine with them;

Reproducible: Always
