maybe put a setBlobDataHandle(xxx) setter in the INSIDE_BLINK block and leave
the UUID setter out until we need to construct these from withing chromium

additionally, if we have already have use case for calling this setter from
inside chromium, include all the params required to cons up a BDH:
uuid, type, size.

    // For deserialization of script values and ipc messages.
    static PassRefPtr<BlobDataHandle> create(const String& uuid, const String&
type, long long size)
    {
        return adoptRef(new BlobDataHandle(uuid, type, size));
    }

+    WebString blobUUID() const;
 
 private:
     WebPrivatePtr<WebServiceWorkerResponsePrivate> m_private;
 };
 
 } // namespace blink
