Doh! I knew I was missing something. What's silly is that I had done
this correctly (lstat + fstat, and dev/ino comparison) in a program I
wrote last year. Oh well...

Perl's chdir, chown, chmod, and chroot should all behave like its stat

filehandle (or nothing for some of them). I submitted an RFE to the
perlbug mailing list regarding this earlier today, right before writing
my previous bugtraq note...
