> Currently all of the DOM structure is stored outside the JavaScript VM.  We're experimenting with the idea of uploading some amount of this state into the JavaScript VM.  At least from these simple experiments, there does appear to a significant amount of performance on the table.

In particular, to get the full advantage of the JavaScript VM's memory management, we'd likely want this state to be understandable (and compactable) by the garbage collector.
> 
> We're just exploring the design space.  The performance characteristics of JavaScript VMs have changed radically since the design of the current bindings.  It seems likely that there are different performance considerations now.  If you're interested in this topic, I'm happy to involve you in more of the discussions.

Please do.  And also please involve the folks working on JavaScriptCore.
