I don't see how that's different from having 'cooperative multitasking' in the JS thread unless you are bound by DOM. You have to send data to the UI thread once in a while? Well why can't you let the UI update in the same interruptions? Of course, that will introduce delays, but if they are noticeable to you then maybe you have a DOM tree that's too heavy in the first place? I'm not saying having the lib is bad, but I don't see a justified use-case for it.
