fix: 🐛 process.exitCode instead of calling process.exit to allow cleanup

[pcace]

closes #429

see #429

The test sometimes failed, i guess because it now takes a bit longer to finish code and exit. after using 2000 it never failed on my machine. Hope thats ok.

I am confused on why we are seeing a message to the parent for shutdown when this message typically sent from parent to child, not child to parent. The parent message handler does not have implementations to deal with this message type.

Perhaps I am missing something, but to me this is not going to achieve the goals of providing the exit code on shutdown. Can't there be another binding for worker.exitCode like worker.exit was binded?

Yes, I have the same question indeed, this message is only send from the main process to the worker right now.

I would expect something like:

worker.exit = function (code) {
  process.exitCode = code
  process.exit()
}

Thanks for your PR @pcace, and sorry for the late reply.

Two remarks:

• Can you have a look at the inline comment of Bean?
• How can we reproduce your issue, so we can test whether this PR actually solves the issue? Is it possible to write a unit test to validate the fix?

[pcace]

Hi there, I am very sorry, but I am not using it anymore, so my testcase is gone.
its totally ok if you close the pr.

[josdejong]

Okido, I'll close your PR. Thanks anyway for your efforts!
