Some progress has been made.

The "global lockfile" (LCKF) part was already there but semi-finished.

It has now, as of version 0.92.6+txn1.1, been completed and bugfixed,
and a "manual recovery" interface has been added to bogoutil (new
options -f and -F that require the parent directory of the wordlist.db
file). 

Details in the announcement on the bogofilter list, see
http://article.gmane.org/gmane.mail.bogofilter.general/8299 or
http://www.bogofilter.org/pipermail/bogofilter/2004-August/006590.html

I still have to do

1. the crash detection (APRT in Pavel's nomenclature) and 
2. monitoring parts and 
3. the recovery code is not yet covered by the self-test suite.

and perhaps

4. add code that automatically resizes the data base's lock tables so
   that bogoutil -d ~/.bogofilter/wordlist.db can complete with larger
   data bases.
