What I did
Manually set thread count for Vitest in CI, because CircleCI reports the wrong number of CPUs (always reporting 32) so the automatic detection doesn't work. This causes too many tests to run in parallel, making them slow and flaky.
Thanks to @jahed for writing https://jahed.dev/2022/11/20/fixing-node-js-multi-threading-on-circleci/ which pointed me in the right direction.
Apart from fixing the flakiness it also reduces the unit test time in CI slightly from 2m14s to 1m45.
