> The configuration is only set when opening the session; that seems unnecessary - it could
be set in the ctor and made final. E.g. when updating the session and localizing new resources
we may theoretically open the session with a new config, but we don't update the config and
only update the files if the session is already open, which seems to imply that it's ok to
not update the config. 
> In most cases, the session is opened only once or reopened without intending to change
the config (e.g. if it times out).
