--- Comment #1 from Kirk McKusick <mckusick at FreeBSD.org> ---
What editor are you using? Most editors follow the safe update practice:

write file to new_name
fsync(new_name);
rename(new_name, orig_name);

The fsync will not return until the contents are on the disk and the rename is
atomic, so it will either point at the orig_name file contents or the new_name
file contents which because of the fsync will be on the disk.
