the reason we tie time-budget in this test (and other similar stress tests) to timeout is to give a test chance to do actual testing in slow configurations (which will set higher timeout factor), for example, runs w/ -Xcomp on debug builds. if we use hardcoded value, the test might spend (almost) all its allocated time to just init and wouldn't perform any testing. ]

so instead of using the hardcode limit, I'd prefer to adjust the multiplication, `0.25` will give you the same 60s w/ current default timeout factor.
