The application is loaded when server starts via Plack::Handler::Apache2. As soon as I query, a lock a placed on the entire db (SQLite doesn't have a row-level lock), and never let go. Any subsequent query, as long as it is a SELECT, works, but any other query that UPDATEs or DELETEs fails.

I don't know what code to post, in the sense that it is my entire application. Of course, there is no problem in using SQLite if use cgi, but I really do want to move to a persistent environment.

Other than the above problem, SQLite is really brilliant. I can't quite imagine anything (CouchDB, MongoDB, or any other new fangled data storage technologies) quite matching what it can do.
