Jest did not exit one second after the test run has completed.

Thanks for this detailed report! I knew there'd be some cases I was overlooking. I'll investigate tonight.

UPDATE: Ah, I see. I couldn't replicate this with npx node@21 node_modules/.bin/jest or npx node@20 node_modules/.bin/jest but it did pop up with npx node@18 node_modules/.bin/jest. Seems the test still passes even with the hang. There is likely some node@18 related issue with no backported fix.

Turns out later versions of Node terminate persistent server connections more optimally than Node@18 does. Explicitly calling server.closeAllConnections() after calling server.close() did the trick.

Thanks again for opening this issue, I learned from fixing this.
