Demonstrating curious behavior with postMessage() and atomics.wait()

atomics-post-message's Issues

Test with Atomics.waitAsync()

Using Atomics.waitAsync() https://v8.dev/features/atomics achieves the expected result

async function sendPostMessageAndWait() {
  console.log('worker A: sending postMessage to B');
  workerB.postMessage('hello from A');

  console.log('worker A: starting wait() (waits forever)');
  const sab = new SharedArrayBuffer(1024);
  const int32 = new Int32Array(sab);
  const {async:result} = Atomics.waitAsync(int32, 0, 0);
  console.log(result instanceof Promise ? await result.value : result);
  
}
