LGTM with mine and @thefourtheye's nits. Thanks for the PR @mtharrison!

Also, can you update the commit title and message to conform to https://github.com/nodejs/node/blob/master/CONTRIBUTING.md#step-3-commit? Specifically, the title and body line lengths. Thanks!

I know this particular document is riddled with you and your, which we should get refactored out later.. can you reword this to avoid adding a new instance of your? Perhaps, Before a module's code is executed, Node.js will wrap it with a function wrapper.
