* Is F_FULLFSYNC important on iOS devices, since they never suffer abrupt power failures, instead shutting down cleanly when the battery level drops too low? (But judging by how long it takes to issue an END TRANSACTION statement in SQLite, that codebase still seems to be using it on iOS.)

I would be worried that (1) the shutdown-before-power-failure mechanism may not be foolproof, and (2) a kernel panic could still leave the truly non-volatile storage in an inconsistent state. -- Greg Parker gparker@apple.com Runtime Wrangler _______________________________________________ Do not post admin requests to the list.
