pm2 is broken because childprocess.unref() fails

[khrj]

When running with:

• __proto__ enabled (applied on top of the changes in #16775)
• PR for pm2 to not use __proto__: chore: bump chalk from 3.0.0 to 4.1.2 Unitech/pm2#5489

pm2 seems to fail because child.unref() failed internally

[khrj]

Note that this is only reproduced when running pm2 for the first time after startup (when it shows [PM2] Spawning PM2 daemon with pm2_home). After that, you need to deno run --unstable -A npm:pm2 kill to reproduce it again

Possibly related missing implementation:

import { createRequire } from "https://deno.land/std@0.165.0/node/module.ts"
const require = createRequire(import.meta.url)

const child_process = require("child_process")
const fs = require("fs")

const pipe = fs.openSync("/tmp/issue.log", 'a')

const child = child_process.spawn("echo", {
	stdio      : ['ipc', pipe, pipe]
})

Unrefing child process is definitely implemented (eg. Vite uses it), but the problem seems to be usage of ipc as stdio.

child_process IPC is now implemented. See #21490

This issue should be resolved as of Deno v1.39.1.
