In the following benchmark, we get GC pause of about 15 seconds because of low memory notification that was sent from WebKit. http://people.mozilla.org/~wmccloskey/incremental-blog/example-pause.html In this case the low memory notification is unnecessary because all memory usage consists of V8 objects, not DOM objects. So in this case V8 can schedule GC itself more optimally.
