All I can suggest is making the server timeout 1000 and the callTimeout 200. The current change makes this test no longer valid.

D'oh, I totally misread how this test works. Works for me if this actually fixes the flakiness

@Trott can we confirm with a stress test? From what I recall of writing this test, launching too many requests was problematic in making the test flaky in a different way. I used to have setTimeout for 1ms which was nearly equivalent to this.

Edit: just got home and started it myself https://ci.nodejs.org/job/node-stress-single-test/1973/

I ran two stress tests and both appear to be green. 🎉
