I changed this to make it clear that the first check throws an exception that
contains interesting data, and the second (the actual redirect) doesn't.

+        var worker = createWorker('http://localhost:8000/workers/resources/worker-target.js');
         worker.onerror = function(evt) {
             log("FAIL: threw error when attempting to cross origin while loading the worker script.");
             runNextTest();
