I wonder if it'd be clearer if it was named:

unregisterAllURLsAndClearMemoryCache()

 
   // Causes all pending asynchronous requests to be served. When this method
   // returns all the pending requests have been processed.
   // Note: this may not work as expected if more requests could be made
   // asynchronously from different threads (e.g. when HTML parser thread
   // is being involved).
   // DO NOT USE THIS for Frame loading; always use methods defined in
   // FrameTestHelpers instead.
   virtual void serveAsynchronousRequests() = 0;
 
   // Set a delegate that allows callbacks for all WebURLLoaderClients to be
   // intercepted.
   virtual void setLoaderDelegate(WebURLLoaderTestDelegate*) = 0;
 };
 
 }  // namespace blink
 
 #endif  // WebURLLoaderMockFactory_h
