Hangs process in Node.js

Hi! 👋

Firstly, thanks for your work on this project! 🙂

Today I used patch-package to patch await-sync@1.0.1 for the project I'm working on.

Here is the diff that solved my problem:

diff --git a/node_modules/await-sync/mod.js b/node_modules/await-sync/mod.js
index 7bb40b0..e13b25a 100644
--- a/node_modules/await-sync/mod.js
+++ b/node_modules/await-sync/mod.js
@@ -20,6 +20,8 @@ function createWorker (signal) {
   return function awaitSync (fn, formatter) {
     const source = 'export default ' + fn.toString()
     const mc = new MessageChannel()
+    mc.port1.unref?.()
+    mc.port2.unref?.()
     const localPort = mc.port1
     const remotePort = mc.port2
     worker.postMessage({ port: remotePort, code: source, ab }, [remotePort])

This issue body was partially generated by patch-package.

This is a thing in v1.0.1. I assume it carries over to v1.0.2 since the update doesn't touch it at all? Can't verify without #7 fixed
