Failures can also be hit with CircleCI test multiplexer:
https://app.circleci.com/pipelines/github/adelapena/cassandra/1387/workflows/0f37a726-1dc2-4584-86f9-e99ecc40f551

CircleCI results show failures on three separate assertions, with a ~3% flakiness for the entire suite.

The same test looks ok in 4.0, as suggested by Butler and this repeated Circle run.
