Links modify the meaning of paths and it is not clear how to react to
this. 

E.g, 

/a/b/c is a link to /a/b/d/e. How do you interpet /a/b/c/.. ?

Will it reduce to /a/b or to /a/b/d ? 

The answer to this question is "open" to interpretation...

BTW, FileUtil.find is protected against recursive links and so on...
