http://api.jquery.com/first-selector/ mentions that using ":first" in query selectors can be a little slow since we can't use the browser's native querySelectorForAll implementation. In my tests, this cut the average time down from 6.70ms to 6.38ms. So, not great, but this function is most frequently called many times in a big while loop, so, better than nothing.
