another bayes oddity

I have

bayes_auto_learn    0
bayes_auto_expire 0
bayes_learn_to_journal 0

add_header all Autolearn _AUTOLEARN_


and indeed, all messages are tagged with

X-Spam-Autolearn: disabled


Nevertheless, the mtime _and_ size of ~/.spamassassin/bayes_journal
inches forward with every delivery.  Why?

Bayes keeps track of when each token last contributed to a
classification, so it knows which tokens to purge during an expiry.
That's the main reason for having a journal.
