Thanks, but maybe I should rephrase my question: does MacPorts provide a way to configure this? I don't doubt sqlite3 allows it, but that wouldn't be of much help if I'd have to go in and hack the source code.

I've noticed the (transient) presence of a file ${prefix}/var/macports/registry/registry.db-journal , which makes me wonder if it's possible to configure the way the registry database is accessed (akin to mysql.conf when using mysql DBs). If I'm not mistaken, registry.db-journal acts more or less like the HFS, EXT3, NTFS (etc) journals work, and should be completely redundant on a COW filesystem (as well as a significant performance bottleneck).
