I just realized that `TimeoutException` doesn't allow you to specify the
original cause. This is a little unfortunate, because it means all the stack
traces will end where we create this class. It looks like there is an
`initCause` method which does what we want though. So I think the constructor
should require a `cause: TimeoutException`, which we set via `initCause`.
