We have SharedArrayBuffer (shared memory-ish) and Atomics (in latest Firefox) so we have multi-threading in JS (whether it's a good idea or not that's a completely different story) but we still don't have the ability for multiple threads to work with the DOM. We need a SharedDOM construct with Atomics. Well, just because multi-core, right? What am I missing?
