The document's completely bogus here, as it's just a shadow page created with
the same URL as the script URL-- doing the same as ServiceWorker might still
make some sense?

[Mike West, 2016/03/03 05:24:26]

Yeah. This should probably read from the script loader. It's not clear to me
that that's the right thing to do, but I think it makes sense given that the
worker will be talking to multiple documents (and should be same-origin with
each).

     m_loaderProxy = WorkerLoaderProxy::create(this);
     setWorkerThread(SharedWorkerThread::create(m_name, m_loaderProxy, *this));
     InspectorInstrumentation::scriptImported(m_loadingDocument.get(), m_mainScriptLoader->identifier(), m_mainScriptLoader->script());
     m_mainScriptLoader.clear();
 
     workerThread()->start(startupData.release());
     m_workerInspectorProxy->workerThreadCreated(m_loadingDocument.get(), workerThread(), m_url);
     m_client->workerScriptLoaded();
 }
