No PR submitted because I don't know which of the directions to go in.\n","author":{"url":"https://github.com/greg-js","@type":"Person","name":"greg-js"},"datePublished":"2016-02-23T14:15:12.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":3},"url":"https://github.com/5385/node/issues/5385"}
