Actually, this one got fixed. (Apologies, I should have resolved this at the time).

The sunspider shell test harness was changed to call the run() function, which returns submillisecond timing, which fixed this.

(Spidermonkey added the same run() function, so that fixes it on our end too).

Here was the changeset (r72842)

        Improved accuracy of command-line SunSpider.

        * resources/sunspider-standalone-driver.js: Use the returned number of
        elapsed milliseconds from "run" and "checkSyntax" instead of measuring
        ourselves, for slightly more accurate numbers.
