As I understand it, Node waits for the event loop to empty (no more async code running) before it exits. But what if you have a connection to Mongo DB for example? Does Node just ignore this connection and exit anyway? What happens if you can't close it programatically because the async operations depend on it?. 4 - Kubernetes waits for a grace period.
