WorkerScriptContextSet?

[lazyboy, 2016/04/14 02:07:53]

WorkerScriptContextSet manages SW ScriptContexts in worker thread in a TLS
variable.
ServiceWorkerData is also stored in worker TLS, so this class can also store
those ScriptContexts.
I've clarified the comment a bit.

+class ServiceWorkerData {
+ public:
+  ServiceWorkerData(WorkerThreadDispatcher* dispatcher, int embedded_worker_id);
+  ~ServiceWorkerData();

Done.
