New issue 3378 by [email protected]: V8 counters and histograms do not
work in Chrome
http://code.google.com/p/v8/issues/detail?id=3378
The backing store for counters and histograms is provided by the embedder
via callbacks. Those callbacks are stored in isolate->stats_table(). In
Chrome, the callbacks are registered in content::RenderThreadImpl::Init
[0]. At that time however, we don't even have an Isolate yet, so we simply
ignore it. Later on, when we try to use counters, we don't have the
callbacks, and regard counters as disabled.
Could this be a fall out of removing the default Isolate?
