Sure it's only in two and a nightly build browsers right now, but I bet this will complicates/advance Javascript.

yeah, multi threading for the masses, but without any synchronization. can this be useful?

(You can fake semaphores with messages... you just have to follow your own rules)

Or a browser developer could just write an engine that runs JS separately, effectively preventing (almost*) all JS from locking the interface**...



* while(!0)alert("")

** Or anything else. By which I mean image and video rendering, which are really the examples Resig cited that I can understand the benefit for. How would workers speed up the raytracing bit? It's still sequential code -- one block (drawing) waiting for another (calculation worker) -- so the multitasking benefit of workers would likely not apply, unless the calculation worker is used multiple times at once... Hmm...
