1019 one. Since most members are shorter than BUFSIZ, this means we will read
1020 the old header, read the old data, write a new inode for the new file, and
1021 write the new data, and be done. This 'optimization' is what comes from
1022 sitting next to a bare disk and hearing it every time it seeks. -- Gnu
