    1 If the disk doesn't have a battery backed cache but BFS is using the cache and not fsync'ing on unmount, surely it would only be an unclean shutdown that could cause this - unless of course the system shutdown completes on another thread before such time as the disk driver has had a chance to fsync. Apologies if my terminology is a little rusty, it's been a while since I read about this aspect of storage / syscall usage.
