Move away from timeouts in more tests.

Not sure why, but all of a sudden Node 0.8 builds are failing on Travis for timeout-using tests. See also e398cfbf3fe7f6b8a16e3ed108c0925075808967 and df5f4951e94b419a9d829346fea6698020a372f7. Since it's bad practice anyway, I'm fixing them as they cause failures.
