Failures can also be hit with CircleCI test multiplexer:
[https://app.circleci.com/pipelines/github/adelapena/cassandra/1389/workflows/0afa9d7a-30ad-44de-af8f-6e75d03c11b2]
CircleCI results show failures on three separate assertions, with a ~2%
flakiness when running the test isolated.
The same test looks ok in 4.0, as suggested by Butler and [this repeated Circle
run|https://app.circleci.com/pipelines/github/adelapena/cassandra/1390/workflows/692e5cae-30f3-4cf9-84ac-5560bbcdcee8].
