Top-level await promise never resolved

https://deno.land/[email protected]/examples/os_signals

According to your documentation, I run and report an error

import { signal } from "https://deno.land/[email protected]/signal/mod.ts";
// Windows 只支持 SIGINT 和 SIGBREAK
const sig = signal("SIGBREAK", "SIGINT");

// Add a timeout to prevent process exiting immediately.
setTimeout(() => {}, 5000);

for await (const _ of sig) {
  console.log("顶级等待承诺从未解决");
}

error: Top-level await promise never resolved for await (const _ of sig) { ^ at (file:///E:/test/deno/deno01/index.ts:667:18)

What version of Deno are you using? What command are you using to run this code snippet? The documentation example works fine on my Mac (running Deno 1.30.0)

I believe this is not a bug but the expected behavior in this case. I made an issue for the same thing a while back (note that the error message was different then): https://github.com/denoland/deno_std/issues/1941#issuecomment-1061293369

Closing this as std/signals was deprecated and removed from the Standard Library a while ago. Please take a look at the OS Signals documentation. If the code there doesn't work for your use case, please open a ticket in https://github.com/denoland/deno-docs.
