KNOWN-BUGS
----------

- It's possible that some kind of file systems (ext3?) relocate the inodes
  even if the file is opened with open(..., O_WRONLY) and is never write
  over its size. This is a nasty problem and I think there is no fix if
  overwrite isn't running as root.
- Sync(2) forces the OS buffers to disk but doesn't force the HD to flush
  the cache. Also fsync() is used, and some linux ioctl(), but I can't
  guarantee that this works under all linux versions and on BSD, solaris and
  so on. Anwway if you run overwrite in Linux 2.[024] the ioctls should do
  the work with IDE HDs.

If you have some fix for some of this problems or you found
bugs not listed here let me known with an email to <antirez@invece.org>
