> When an input CAS is returned from a Cas Multiplier, an Aggregate immediately 
> returns it back to the client with no check if the subordinate CASes (those 
> produced from the input CAS) are still in "in-play" in other delegates. Upon 
> receiving the input CAS reply, the client assumes success and sends a CPC. 
> Meanwhile, the CASes still in-play may cause Exceptions and termination of the 
> aggregate. The CPC sent to the service may never be replied to leading to a 
> hang.
