Subversion's core usage of BDB arguably helped to advance the state of the
Berkeley DB art. Multi-process support has been officially part of the
Berkeley DB API since at least the 4.4 release (Branko will remember the
original DB_REGISTER work, I'm sure). And just few years ago I was even
having private conversations in which ex-Sleepycat folk were trying to urge
the Subversion project to further embrace Berkeley DB, specifically its
built-in database replication support. Single-process (via a brokering
daemon) is still the recommended approach, of course, but my understanding
is that it's no longer considered the Only Right Way.
