Bug: wrong return value for node worker_thread.terminate()

[marvinhagemeister]

The .terminate() method is supposed to return a Promise, see https://nodejs.org/api/worker_threads.html#workerterminate , but we return undefined instead. This is one of the reason the tinypool library is unable to terminate workers.

Steps to reproduce

1. Create file worker.js with some content like console.log("worker")
2. Create file main.ts with these contents:

import { Worker } from "node:worker_threads";
import * as path from "node:path";

const worker = new Worker(path.join(import.meta.dirname!, "worker.js"));
worker.terminate().then(() => {
  console.log("terminated");
});

3. Run DENO_FUTURE=1 deno run -A main.ts

Error

$ DENO_FUTURE=1 deno run -A main.ts
worker
error: Uncaught (in promise) TypeError: worker.terminate(...).then is not a function
worker.terminate().then(() => {
                   ^
