// behavior) and do our own setup, running and teardown.

// This is a little unfortunate as it means that we can't report results that
// directly compare with v8-bench.js, but hopefully our results will be more
// stable (as we have less magic in how many iterations we run), and we shall
// still provide useful information if a test regresses.
