random place for this comment, but it would be even better if the
ObjectBackedNativeHandler functionality were exposed via composition not
inheritance.

not now, maybe not ever :)

Thinking about it. We shall see!

   RouteFunction(
       "GetFileSystem",
        base::Bind(&FileBrowserPrivateCustomBindings::GetFileSystem,
                   base::Unretained(this)));
 }
 
 void FileBrowserPrivateCustomBindings::GetFileSystem(
     const v8::FunctionCallbackInfo<v8::Value>& args) {
   DCHECK(args.Length() == 2);
   DCHECK(args[0]->IsString());
   DCHECK(args[1]->IsString());
   std::string name(*v8::String::Utf8Value(args[0]));
   std::string root_url(*v8::String::Utf8Value(args[1]));
 
   blink::WebLocalFrame* webframe =
       blink::WebLocalFrame::frameForContext(context()->v8_context());
   DCHECK(webframe);
   args.GetReturnValue().Set(
       blink::WebDOMFileSystem::create(
           webframe,
           blink::WebFileSystemTypeExternal,
           blink::WebString::fromUTF8(name),
           GURL(root_url)).toV8Value());
 }
