We should put a templated version of this in bindings somewhere. Everyone ends
up coding this silly no-op function.

I think it should be possible to do something fancy that deduces the right
signature, so you just do:

inspector->Listen(9898, base::Bind(&mojo::EmptyFunction)).

+
 void InspectorServiceImpl::Inject() {
   if (!view_)
     return;
+
+  mojo::ServiceProviderPtr inpector_service_provider;
+  view_->shell()->ConnectToApplication("mojo:sky_inspector_server",
+                                       GetProxy(&inpector_service_provider));
+  InspectorServerPtr inspector;
+  ConnectToService(inpector_service_provider.get(), &inspector);
+  inspector->Listen(9898, base::Bind(&Ignored));
+  inspector.WaitForIncomingMethodCall();
   view_->web_view()->injectModule("/sky/framework/inspector/inspector.sky");
 }
 
 }  // namespace sky
