Thanks, that's good to know. So a word-processor-like application might try implementing its own simple global lock (eg with a lock file) and then tell SQLite to use nolock=1. I'm not sure I'd feel very comfortable doing that but it seems OK in principle. I wish Subversion would offer an option to do something of the sort for its working copies, now it has an SQLite database in there.
