AFAIK, checkpoints are application-specific, but SQLite prohibits second writer until first one committed its transaction and released database lock. So there can't be such thing as "two writers, both writing to the same DB". If one writer writes, another one is locked out and waits. And btw checkpoint cannot be completed if there are some application with transactions that started before last commit to the database was made. Although partial checkpoint is possible in such situation.
