boomerang always comes back, except when it hits something

(function() {
  if (window && window.requestAnimationFrame) {
    window.BOOMR = window.BOOMR || {};
    window.BOOMR.fpsLog = [];

    function frame(now) {
      // window.BOOMR.fpsLog will get deleted once Boomerang has loaded
      if (window.BOOMR.fpsLog) {
        window.BOOMR.fpsLog.push(Math.round(now));

        // if we've added more than 30 seconds of data, stop
        if (window.BOOMR.fpsLog.length > 30 * 60) {
          return;
        }

        window.requestAnimationFrame(frame);
      }
    }

    window.requestAnimationFrame(frame);
  }
})();
