The request callback is called and the 'upgrade' event doesn't fire.  I'll bisect.\n","author":{"url":"https://github.com/bnoordhuis","@type":"Person","name":"bnoordhuis"},"datePublished":"2015-01-27T21:29:50.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":6},"url":"https://github.com/627/node/issues/627"}
