Oh, I just remembered a couple that does: find and du. So there are a 
few. And special treating in this case just means don't go down there, 
as it will be repeating information already examined. Makes total sense, 
and I don't think it's a correct representation saying that they are 
useless because these programs skip them. It's just that they should not 
be traversed, since they already have been.

But these two programs also already have to deal with loops (imagine that).
