 from `man 2 write`:

 {{{
        A successful return from write() does not make any guarantee that
 data has been committed to  disk.   On  some  filesystems,
        including NFS, it does not even guarantee that space has
 successfully been reserved for the data.  In this case, some errors
        might be delayed until a future write(2), fsync(2), or even
 close(2).  The only way to be sure is to call fsync(2) after you
        are done writing all your data.
