Major - P3 One of my PRs failed on Windows in test_checkpoint04.py with:

The test assumes the time needed is measurable and Windows often has very coarse timings.
self.assertLess(prep_min, time_min)
self.assertLess(prep_max, time_max)
self.assertLess(prep_recent, time_recent)
self.assertLess(prep_total, time_total)
These should either accept assertLessEqual or specifically check for 0.
