I have a vague memory that Google is supposed to not play well with 410s.
If the crawl-and-noindex doesn't do it, perhaps try a 404 for a bit and see if it helps?
But, unless widgetworld.com has bad links that you don't want affecting the correct domain, I would have 301ed each page to the correct page, myself. :)
