It does not have to run asynchronously. I will remove it.
We need the `transitionState` because it might happen that we cannot
properly cancel all `ExecutionJobVertices`. E.g. if the `SlotOwner` cannot
return the allocated slot. This is currently not the case, but we should guard
against it if this should change in the future.
