The timeout here is the same issue as issue #11887, but the "deletion failed" errors are not. It's possible they're the same issue as issue #18827, although there we never saw any indication that the deletion was failing due to the file being locked. Is it possible that the tests are running multiple instances of pub simultaneously?
