> References to Task objects may under some conditions linger longer than for the lifetime of the task. For example, in case of local network channels, the receiving task may have a reference to the object of the task that produced the data.
> To prevent against memory leaks, the Task needs to release all references to its AbstractInvokable when it shuts down or cancels.
