This failure is kind of known and discussed in [1]. Just to make it explicit: this test failure doesn't really surface a regression, the reftable code already failed for concurrent writes before. I fixed that and added the test that is now flaky, as the fix itself is seemingly only sufficient on Linux and macOS. I didn't yet have the time to look at whether I can fix it, but should finally find the time to do so today. Patrick [1]: <20240927040752.GA567671@xxxxxxxxxxxxxxxxxxxxxxx>
