public interface ExternalTaskCompletionHandle
ExternalTask.doExecute(ExternalTaskCompletionHandle).
 
 Flow framework is not thread safe and expects that all asynchronous code is
 executed in a single thread. Currently ExternalTaskCompletionHandle is the
 only exception as it allows complete() and fail(Throwable)
 be called from other threads.
