You don't even necessarily need to copy all the JS objects passed from one thread to another if you're willing to do some COW or other tricks. Maybe I'm wrong, but at least it seems a premature optimization to declare that shared database storage between page and worker is necessary for performance.

We all, like sheep, have gone astray, each of us has turned to his own way; and the LORD has laid on him the iniquity of us all."
