Does the WorkerPermissionClientProxy retain the SecurityOrigin object?  It's not
thread-safe....

No, it's only used for initialization.  I can add a comment to note that the
embedder should not retain it.

     OwnPtr<WorkerThreadStartupData> startupData = WorkerThreadStartupData::create(url, userAgent, sourceCode, startMode, contentSecurityPolicy, static_cast<WebCore::ContentSecurityPolicy::HeaderType>(policyType), workerClients.release());
     setWorkerThread(SharedWorkerThread::create(name, *this, *this, startupData.release()));
