this is the case with regular filesystems. softupdates makes it so you're not "hosed". rather, your file is left "untouched" if the system loses power during a write.

the "syncer"'s last step is to mark that the data is complete after it is all written to the disk.

and yeah i said i'd bow out, but ya gotta fight FUD as you see it.
