By a quick look, i have some ideas of where test flake can happen, and i think we can reduce concurrent workers from 4 to 2 (given unbuntu-latest probably has 4 cores)

Plus, i think usually loadfile could be a better distribution strategy than the default in concurrent runs scenario since tests from the same file will go to same worker now.

not sure how much it will help, but i think it can help a bit, maybe we can give it a try? WDYT? @leekeiabstraction @fresh-borzoni

there are some other improvements can be made too to improve test stability, and can share later.

Thank you, let's try this as a quick fix, if you can propose some improvements in tests - also much appreciated 👍
