True.  But a good protected mode OS pretty much requires this, or it
will have many memory management problems.  For an OS that doesn't
support memory protection, this is just one more thing not to 
protect against.

I remember in early versions of VAX/VMS you could rename directories
into themselves.  Without protection against this, disk blocks will
disapear, which is what happened.
