There was a problem hiding this comment.
why introduce a buffer instead of directly logging to t? In order to minimize noise in test output? In that case maybe add a comment explaining the why.

Yes, exactly. So we only emit the log entries if the test fails, not if it succeeds. I will add the comment, thanks!

What does this PR do?
Add logging when output reloading test fails.
Why is it important?
While we made some concurrency fixes to the output reloading code path in #17381, it appears there might still be a race condition somewhere. So far we have only seen this show up occasionally in CI (see test failures captured in #17965) and have not been able to reproduce it locally. So this PR will allow us to see logs of what was happening when the output reloading test fails.
