Description

[David Mandelin [:dmandelin]]

From bug 643615 comment 4. This is probably good for a small win on deltablue.

function f() {
    for (var j = 0; j < 100000; ++j) {
        var a = [];
        for (var i = 0; i < 100; ++i) {
            a.push(i);
        }
    }
}

var t0 = new Date;
f();
print(new Date - t0);
