While trying to figure out XMLHttpRequest works with tasks and all I noted that Web Workers depends on HTML5 for the definition of a number of them. In HTML5 it is stated that each task is associated with a Document object. Web Workers do not have a Document object. This seems like an issue.
Also it is not clear whether Web Workers reuses the generic task sources defined in HTML5 or whether it has any task sources at all, for that matter. -- Anne van Kesteren http://annevankesteren.nl/
