[webkit-dev] WebKit branch to support multiple VMs (e.g., Dart)

At a high-level, the idea is pretty simple. We want to be able to run
another VM along a JS one. For example, if we see a Dart script on a web
page, we want the Dart VM to be able to handle it. If we see a JS script,
we want the JS one to handle it. Similarly, if an event listener on a page
is triggered, we want to forward to the appropriate VM to run the user
The changes here are mostly about refactoring some classes (e.g.,
ScriptController, ScheduledAction) to add that extra dispatch.
I'm not familiar enough with the JavaFX model, but this may be useful if
you want to provide direct access from Java to the DOM via Java bindings.
Do you have a pointer on how you're handling multiple VMs in WebKit today?
