I cannot reproduce this. I need to slow it down such that tests take 20s to get this error (and it says 10 valid examples in 1.30 seconds and the test suite took 2.9s). Runing the tests in a loop without CPU limitation (tests run in 1.88 seconds) doesn't trigger the bug. I don't intend disabling this test which seems important because there is not enough CPU to run the test (even if this is not a timing-related test). Like for memory and disk, I understand that test suites have some expectation on how much CPU the environment should provide (otherwise, we have to disable all timing related tests). -- "You have been in Afghanistan, I perceive." -- Sir Arthur Conan Doyle, "A Study in Scarlet"
