<pre>Here's the case that originally struct me as wrong:
function f(j) { for (var i = 0 ; i < 10000000; i++) j = (j ? j * i : 1) ^ (i & j); };
var start = new Date; f(); var end = new Date; print("2nd: " + (end - start) + "ms");
var start = new Date; f(); var end = new Date; print("3rd: " + (end - start) + "ms");
First run is 433ms, second run is 137ms.</pre>
