Note that although the documentation says only the file handle is synced, in practise many filesystems actually sync the whole filesystem writing out all pending data for all files. The reason is the underlying filesystem is written to carefully write content (especially meta data) in a particular order, to ensure robustness against power losses, make syncs easier to manage, and make fsck easier. Trying to sync just the one file handle is too complicated, so they sync everything. You need to watch out for other write activity on the system, not just SQLite.
