Essentially restating Marco's concern, increasing timeouts has the side
effect where performance regressions are not noticed. i.e., a new bug that
causes a test to take longer, but still pass, is not detected. With the
original lower timeouts, the test would fail with a timeout. So a little
bit of the value of the tests is lost, and it's difficult to address later.
