These being said you should flush all buffers by ``xSync'', or disable all buffering and immediately pass all data down after ``PRAGMA synchronous = OFF'' (http://sqlite.org/pragma.html#pragma_synchronous). That is a designed behavior of a VFS driver. If you didn't comply with that schema, you would play on your own with SQLite's sources. -- best regards Cezary H. Noweta
