Bayes locking

[Ole Nomann Thomsen <on...@uni-c.dk>]

Hi, I've configured this:

 bayes_learn_to_journal  1
 bayes_auto_expire 0
 bayes_journal_max_size 0

I assumed that this would cause any bayes-learning
to land in the bayes_journal file, only to be incorporated in
the main bayes files whenever I ran "sa-learn --sync". Thus
keeping bayes_toks, bayes_seen readonly for most of the time.

But what I'm seeing is no change: lots of lockfiles: 
"bayes.lock.<host>.<pid>" and bayes_toks, bayes_seen getting 
updated constantly.

Am I wrong in my assumption or have I just configured bad?
