Hmm. They might be. But the threading aproach described in the link you posted is sort of a all or nothing thing. You can split you're long-running task into a thread, but unless everything else your app is doing is also in this kind of a thread, it won't run. Also, these are cooperative threads. That means that your program has to explicitly say "ok, I can be paused for a while now and let other threads run". There's no preemption as in conventional threads, where a scheduler will divide the time between the threads. So.. you really have to program all of your application with this in mind. Also, you have to be using js 1.7 to even consider generators, and that limits you to Firefox 2.x only. If you are willing to create that kind of a requirement on your clients, Google Gears might be the perfect fit for your application: http://code.google.com/apis/gears/ http://gears.google.com/ This is a browser extension that (among other things) allows you to create real threads from javascript and run them asynchronously.
