I tried to make these explicit, but it turns out a lot of places rely on this.

+    ResourceRequest(const KURL&);
     explicit ResourceRequest(CrossThreadResourceRequestData*);
+    ResourceRequest(const ResourceRequest&);
+    ResourceRequest& operator=(const ResourceRequest&);
 
     // Gets a copy of the data suitable for passing to another thread.
     std::unique_ptr<CrossThreadResourceRequestData> copyData() const;
