No, what you have looks ok. Only one more suggestion I think, I seem to remember some-one having a similar problem and it went away when they used Mongrel instead of Webrick, though I do not understand why. I can only suggest you try that, so start the server with ruby script/server --mongrel and see what happens. I always use mongrel as for me it loads much faster.
