Spec: http://www.w3.org/TR/2012/CR-workers-20120501/#sharedworkerglobalscope
The name attribute must return the value it was assigned when the SharedWorkerGlobalScope object was created.
So we should have a test to check it, there is a related test "fast/worker/shared-worker-name.html" already,
but it doesn't cover this.

(test11.worker.port.onmessage):
(test11):
