Upgrading to use Berkeley V4 databases?

[Quanah Gibson-Mount]

We've noticed that SpamAssassin still uses the rather inefficient V1 BDB 
databases for Bayes via DB_File.  Is there any move to re-work this to use 
the more efficient V4 database types, or is all BDB support essentially 
dead-ended (i.e., is only the mysql backend bits going to be further 
developed)?

Thanks,
Quanah
