> 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.
