That's only true in theory. In practice, you'll be rate-limited first. Even if you aren't, the database won't be the bottleneck because SQLite is so fast. Their Ruby on Rails stack will suffer thread starvation way before the WAL grows. Rapid requests still leave microsecond gaps between context switches for SQLite to run an automatic checkpoint. To actually make SQLite stall, you'd need an endpoint that lets you hold a massive write transaction open indefinitely, which lobste.rs doesn't expose anyway (I hope).
