summary
Finds and fixes a Node.js core bug that drops child-process messages when using ES modules by adding a pending message queue and delaying delivery until a listener exists. Changes touch internal spawn/IPC code: replace direct emit with a wrapper, capture emitted args, handle newListener to flush queued messages, use SafeSet/Reflect.apply and move the iterator work outside loops. Adds automated tests, builds locally to iterate quickly, lands in Node 17 and is backported to 14 LTS, so the fix is released and working for thousands of packages.
