no need to include WebVector.h

+
+namespace WebKit {
+    class WebString;
+    class WebSharedWorker;
+    class WebURL;
+
+    class WebSharedWorkerRepository {
+    public:

as mentioned over IM, i don't think stddef.h is the proper include for
uintptr_t.  i'm referring to what WebCommon.h includes.

+        // Caller is responsible for freeing the returned object. Returns null if a SharedWorker with that name already exists but with a different URL.
+        virtual WebSharedWorker* lookup(const WebURL&, const WebString&, DocumentID) = 0;
+
+        // Invoked when a document has been detached. DocumentID can be re-used after documentDetached() is invoked.
+        virtual void documentDetached(DocumentID) = 0;
+
+        // Returns true if the passed document is associated with any SharedWorkers.
+        virtual bool hasSharedWorkers(DocumentID) = 0;
