They *may* be disposed - they will only actually be disposed when v8 does a garbage collection (but any v8 API call can trigger a gc, so you can't really control when that happens). > 2) Objects referenced by Local<>s will be add to a list hold by the > HandleScope object, and while disposing HandleScope object, it will check > all objects in this list whether it should be disposed.

I don't think it makes a difference. You should note that you have to explicitly manage the lifetime of a persistent handle, e.g. you'd have to Dispose() it when you no longer need it. Using persistent handles where locals would be appropriate sounds like a recipe for blowing your foot off to me. - Bert
