Explore multithreaded programming in XUL: "As you create cross-platform desktop applications using XUL, you also can enhance your skills with JavaScript, CSS, and even HTML. XUL's cross-platform capabilities are not a collection of least common denominator features. Instead, XUL gives you the kind of power that you might expect from a desktop application toolkit, including access to native threads. You can even access native threads directly from JavaScript, writing code that executes in parallel. In this article, you will examine the multithreading capabilities of XUL, and create an application that uses multiple threads to retrieve data. You will take a classic IO-bound application, one that accesses multiple remote data sources over the Internet, and speed it up through multiple threads in XUL. The application will allow users to view and compare anonymous results of three popular search engines: Google, Yahoo, and Bing from Microsoft®."
