Several thoughts on this:

  1. Thanks a lot for @vstinner and @pablogsal for providing extra information about this crash
  2. I feel obligated to fix this due to bpo-45052: Unskips a failing test_shared_memory_basics test #28182 (comment)
  3. This is not a trivial test flow, I hope that I got it right, but very careful review is required (we cannot even catch this in CI, what was the initial problem)
  4. I hope, that this won't happen again! 👍

Thanks a lot for the fix @sobolevn!

Does this need to be backported to something before 3.10?
