extracting files with tar can corrupt the file system

[M.RUBIN]

I actually had to unlink() a directory a few months ago... it had been
corrupted (I'm not sure whether it was a disk error, or an untrained
person with the root password) so as to contain a hard link to itself,
other than "." .  "rmdir" refused to remove it on the grounds that it
wasn't empty, so I had to write a program calling unlink() to zap it.
