As long as we have safe write order to database file it should not be corrupted due to unexpected interrupt. Even FW is not needed for it - nothing prevents OS to flush cache to the disk after application was interrupted.
Actually, kernel does it before interrupt.
I prefer to save database with all possible measures. The user has a chance to avoid engine shutdown on signal caught using fb_shutdown_callback() but that will be his choice. Default should be safe.
Embedded mode cannot be safe by definition: it shares address space with unpredictable user code. Client-server mode is safe without shutdown on client side. I can live with fb_shutdown_callback(), but still would like client library to be a little less "active".
