The parent could specify to the browser that the new page should not be made visible to the user (in the use case where the new page will be processing AJAX replies using the DOM Parser) or visible (in the use case where the developer is debugging the web worker and wants to see calls to window.alert()). So a web worker is like another tab in the browser that can communicate with the spawning tab via messages only. So web worker API is really just a intra-page communication interface with pages able to open new pages and keep them invisible. Tabs in a browser are like independent processes. And it seems web-workers is more about processes than threads. This allows one web application (process) to spawn another and talk to it. This will not interfere with or conflict with the idea of having javascript have threads in the future, but would complement it. With multi-processors becoming common, I think javascript will soon follow C++ in adding thread support.
