A worker is created with `new Worker(__filename)`. When you pass a `Buffer` via `worker.postMessage(buf)` and then read `buf.length` on the main thread afterward, the buffer is still fully intact. But when you pass an `ArrayBuffer` in the transfer list, reading it afterward shows length 0. Why?
const { Worker, isMainThread, parentPort } = require('node:worker_threads');
if (isMainThread) {
const w = new Worker(__filename);
const ab = new ArrayBuffer(8);
w.postMessage(ab, [ab]);
console.log(ab.byteLength); // ?
}
