there's a little race condition: a session is taken down and its associated
write buffers are cleared, but there could be imsgs from the RDE for that peer
(e. g. UPDATEs) in the read buffers for the pipe to the RDE or buffered in
the RDE or somesuch. Thus, in session_update(), explicitely check for the
session state and just drop the message if the session is not in state
ESTABLISHED.
