        https://bugs.webkit.org/show_bug.cgi?id=20718

        1.052x on SunSpider
        2.29x on date-format-tofte

        Lots of real sites seem to get many hits on this cache as well,
        including GMail, Google Spreadsheets, Slate and Digg (the last of
        these gets over 100 hits on initial page load).
