I'm not sure if you're kidding :) No, you still need all of the parent/child communication. if a child tab dies, who cleans up the mess? If the user changes rendering preferences, how do you update all the client process? At the very least there's some infrastructure to coordinate parent and children. It's likely they do clever things so each visible window can be rendered by multiple processes, without the ui getting fubared.
