Eh, maybe not in this case, but it would be nice to have it.

I did it locally, so it follows the symlinks with the current 
listRecursive (call a new listRecursive for each item that is a 
directory and a link) *without* any guard against infinite recursion 
and I *tested* it with infinite recursion. I suspected an infinite 
loop. For my surprise it wasn't infinite at all. After some time it 
simply didn't follow the link. I verified in Midnight Commander and 
there as well, after some depth the links are not valid. Konqueror 
gives an error as well: "The file or folder [long path comes here] does 
not exist." I suspect this is because of the limitation of a path name 
length on the file system. The question is if there are filesystems 
with no such limitations, or in other words, can be there a real 
infinite recursion?
