Right. Emphasis on the 'should' :-) I haven't actually reviewed the proposed changes, just gave them a cursory look. This was just a guinea pig test run experiment to see if any tests would fail consistently and try to catch early mistakes.
I intend to do a more thorough review in the coming days.

The state management in the HttpServer is far from obvious - and stop() relies on the state to be accurate. stop() happens asynchronously, which adds opportunity for more races. That failing test is kind of timeout dependent - so it is possible that it will fail on overloaded machines. That said - I didn't see evidence in the log that the test was executing slower that usual, and I haven't seen that test failing before in the CI. I will need to investigate more (which will take time).
