Shutdown hooks do not trigger process "exit" event

[thomaschaaf]

Is there an existing issue for this?

• I have searched the existing issues

Current behavior

Shutdown hooks calls process.kill when it has finished the shutdown this skips process Event exit getting called.

https://nodejs.org/api/process.html#event-exit the exit event is used by e.g. pino (using on-exit-leak-free) to flush the logs before exiting.

/~https://github.com/pinojs/pino/blob/ad864b7ae02b314b9a548614f705a437e0db78c3/lib/transport.js#L10-L19

Minimum reproduction code

https://codesandbox.io/p/sandbox/sad-noyce-6zrk6c

Steps to reproduce

1. Start the project
2. See main.ts "NEVER CALLED" is not logged
3. change shutdown hook to use process.exit(0) instead
4. Start the project
5. See main.ts "NEVER CALLED" is logged

Expected behavior

https://nodejs.org/api/process.html#event-exit should be called
