Explicitly delaying tests is a simple effective strategy to avoid these issues, but should be avoided where possible. Switch from a delay-based strategy to instead backdating all file changes using test-tool chmtime, where that is an option, to shave 9 seconds off the test run time. Don't update test cases that delay for other reasons, for now at least (4 seconds).
