What version of Bun is running?

0.4.0

What platform is your computer?

Darwin 20.6.0 x86_64 i386

What steps can reproduce the bug?

1. create server.js file with following content:

const http = require("node:http");

const server = http.createServer((req, res) => {
  res.write("hello");
  res.end();
});

server.listen(4000, () => {
  console.log("listening", { pid: process.pid });
});

process.on("SIGINT", () => {
  console.log("closing", "sigint");
  server.close(() => {
    console.log("closed");
  });
});

3. run command below

bun server.js

4. Stop process using Ctrl+C or run command kill -int <pid>

What is the expected behavior?

Process should output:

closing sigint
closed

What do you see instead?

Callback registered with process.on("SIGINT", callback) is not called.

Additional information

This feature is important to support graceful shutdown in cloud env like kubernetes.
