> The following execution order will cause an invalid state transition in the {{TaskRuntime}}:
> 1. Task completes, state not yet changed.
> 2. Close {{ContextRuntime}}, finds out task's {{CloseHandler}} not bound, throw an Exception, but Exception has not yet propagated upwards to change state to {{Failed}}.
> 3. Task changes state to {{Done}}.
> 4. Exception propagates upwards, state changed to {{Failed}}. Inconsistent state transition.
