As the draft reads now, when to clean up state is implementation 
dependent.  You said so yourself :-)  So the draft allows a Data Source 
to e.g. set a timer to some large value and not clean up state until it 
fires and claim that it complies.

Text that says that state must be freed when the Read Response is acked 
(or sooner) fixes this.
