Can anyone on the list help me with the shared memory details question described here: [Does `postMessage` or yielding to the event loop or similar sync shared memory?][1]
It seems like Lars T. Hansen's Mandlebrot example [here][2] also expects memory to have been synchronized/updated as of the receipt of a `postMessage` message (when a worker is done, it triggers a `workerDone` message making the main thread redisplay), but there's an `Atomics.store` involved there. Just trying to get a clear idea of when (and whether) one can reliably, in-specification trust that a thread will see updates from other threads without using `Atomics.load` or similar to do every single read. Hansen's Mandlebrot example uses a lock on a single element via `compareExchange`. My experiment that never sees a stale read doesn't use `Atomics` at all (but see the first link above for details). Thanks in advance, -- T.J.
