parallelized logs are out of order

[2bndy5]

@jnooree The logs are out of order. The multi-threaded logs appear after the "posting comments" step (which is the last step). Since our workflow has verbosity set to debug, we can see all the logs from the captured output of clang-tidy and clang-format.

Is there a reason why sys.stdout() would only show output after the loggers are destructed? This might be specific to GitHub Actions runners.

raw logs in question
