I will investigate.

My point of view is that if I run `while :; do cd p; done`, then cwd will
point to .. Yes, you can go up and down, but you can' t know at which
point of the tree you are. Maybe I miss something...

I know nothing about POSIX...

rm (GNU fileutils) 3.16 is not able to remove that kind of tree. It try
to give as parameter to rmdir the fullpathname longer than PAGE_SIZE
chars, so rmdir fail returning -NAMETOOLONG.

Well, if this is out of standards I will reject the patch also for me.
