Certainly (1) and to some extent (2) could be made less bothersome by
resetting the session-id with each new site to which a request is sent
(that is, a session id is invariant for all requests to a particular site,
from client startup to termination, but required to vary in requests to
each new site).  Wasn't this proposed during the discussion of session-id
in January/February?  I'm not seeing a need for the session-id to remain
constant between different sites.
