--- Comment #3 from Joseph Pecoraro <joepeck at webkit.org> ---
Running with `jsc`:

```
var stringArray;
var stringCount = 10000000;
var allocateMemory = function() {
    stringArray = new Array(stringCount);
    for (var i = 0; i < stringCount; ++i) {
        stringArray[i] = String(i);
    }
}
allocateMemory();

var start = Date.now();
var snapshotObject = generateHeapSnapshot();
var end = Date.now();

print("" + ((end - start) / 1000) + " seconds");
print("" + (JSON.stringify(snapshotObject).length / 1024 / 1024) + "MB");
```

On my Mac Pro this takes ~20s and the JSON string is ~500MB.
