Absolutely. There are circumstances where releasing common storage is just not possible while at the same time preserving system integrity and the software has no option to "orphan" it.
Obviously developers try and keep that amount to the smallest possible they can and sometimes use techniques to defer release until known to be safe. Other techniques I have seen include reusing common storage for the next instance of the product if previously stopped or inactivated. With HVCOMM, products can now have less impact below the bar which is a good thing. Rob Scott Rocket Software.
