Actually, I believe that the problem is that there's a lot of code that 
assumes that there is a single directory class that can be asked for things 
like:

* filename separator
* absoluteness
* root directories

etc.

And of course it's being used to answer queries having to do with arbitrary 
path names.

But I think that since there is assumed to be a global namespace for files, 
then we should make sure that the file directory classes can all respond to 
isAbsolute:.
