Why does it make sense to get name A in the following scenario then?

	user 1 creates file A
	user 1 hardlinks this to B
	user 1 gets the "real name" of A
	user 2 deletes file A
	user 2 creates a new file called A
	user 1 tries to access A and gets something unexpected

Corner cases and their handling *is* important.  Find another way to do
whatever it is you're thinking you can do with "the real name of a vnode".
