I won't qualify that as a bug, this is mainly noise. Still I agree that
it would be cleaner to make more efforts in finishing the connections
when the session goes down. You would roughly just need to register an
on_shmem_exit callback which loops through all the connections to finish
them. Now would we want to slow down the session shutdown just for
that? I am less sure particularly if there is lag between the remote
and the local servers.
