fast/events/mouse-cursor-change.html fails sometimes on Mac Debug WK2. I could reproduce locally on a MacBook Pro like this, using more processes than the machine has CPU cores: run-webkit-tests fast/events/mouse-cursor-change.html --repeat 1000 -f --child-processes=20 --no-retry This test uses a timeout of 50 ms. I don't see any way to avoid having the intrinsically inadequate timeout, but bumping it to 200 ms makes the test reliable for me locally.
