C was the language I thought to do this in. Thanks for this code - I 
didn't get past the thinking-about-it stage because I've never done any 
file handling in C before (in my defence, I did complete a compiler 
project with C in uni).

   $ ./godir
   .                              1041563
   ..                             224420
   godir                          1041568
   godir.c                        1041561
   $ ./godir /Volumes/CLEARLIGHT/foo/legoland
   .                              731381
   ..                             772975
   èÿÿÿvk␀␀..␀␀   169384

Unfortunately, having found the inode number:

   $ find /Volumes/CLEARLIGHT/foo/legoland -inum 169384
   find: /Volumes/CLEARLIGHT/foo/legoland/èÿÿÿvk␀␀..␀␀: 
File name too long
   $ find /Volumes/CLEARLIGHT/foo/legoland -inum 169384 -delete
   find: /Volumes/CLEARLIGHT/foo/legoland/èÿÿÿvk␀␀..␀␀: 
File name too long

`-print0 | xargs` gives the same result. With the benefit of Mr 
Tilliard's code, I'm gonna have a crack at writing something to unlink 
$1.
