> On closing a 0-10 connection from management (or Broker shutdown) currently consumers are closed, but the protocol layer's session resources remain even after the connection itself is closed (ServerConnection#closeAsync)
> The work of QPID-6450 exposed this as a problem.  It introduced a VHN scoped task executor which is closed as the VHN is closed.  In the current arrangement this means that it is the Port that attempts to release the session's resources, leading to a task executor as the session tries to schedule the destruction of its model object on the now closed task executor.
