Here is the script I sent to Marcin:

@name = split '/', $ARGV[0];
for($i = scalar @name / 2; i >= 0; i--)
{
    $head = join '/', @name[0..$i];
    $ARGV[0] =~ /$head.*$head/ and die "Oh no! A loop! Probably."
}

Another way to do it would be to assume that any file with exactly the same
name, size, flags, and times was a duplicate, but that would involve
checking the database for each file, slowing things down.
