It can happen that the connection and server is closed before the second
reponse has been processed by server. In this case, the
res.setTimeout() callback will never be called causing the test to
fail. Fix this by only closing the connection and server when the 2nd
has been received.

Fixes: #11768

may be worthwhile adding in common.mustCall() for the various callbacks in this test.

I thought of that but it's tricky because the number of times the callbacks are run depends on when the timer fires. I can wrap the http.createServer() callback though

I don't know if I can wrap the http.createServer() callback either as I'm not sure it's going to be called always 3 times.

Stress test on FreeBSD Wrong PR
Stress test on FreeBSD master for comparison

Any other platforms that we should stress test?

EDIT: It seems like the test is failing on the PR branch at a similar frequency to master when run in parallel.

@gibfahn the first stress test does not seem to use the code in this PR. I've started a new one: https://ci.nodejs.org/job/node-stress-single-test/1132/

@santigimeno sorry about that, had to rerun several times, must have got the PR number confused at some point.

Stress test on master failed while stress test with this PR passed.

This might still be flaky, I currently don't have time to investigate (node-test-binary-arm#8941):
