This hasn't got much to do with the protocol IMHO, everything to do with the choice of database. BDB 4.0.14 does, indeed, have fine-grained locking and transactional (roll-back) logging. I can completely rebuild my Openldap 2.1.14 database from the latest (db_checked) log file and nothing else - nuts to those who think that slapcat and slapadd are sufficient for making backups. And 2.1.14 is umpteen times as fast as 2.1.13, too. For that matter, at least at the last telling, MySQL doesn't have transactional logging, so what?
