Then, do you mean "does it do anything *still*"? Have you any reason to think it doesn't? AFAIK the journal is only used for the db backend, and the point of it is to avoid frequent write-locking. The default is to only journal token timestamps, which are only needed during expiry. bayes_learn_to_journal journals all updates, but then learning doesn't take effect until the sync is done.
