I believe that .. can be unlinked by the super user using the unlink() call.
At that point, a link of .. to . would leave a closed subtree.
This subtree could then be used safely... (I think).

This should probably be done only in a newly created directory, since 
some code may make assumptions about the location of .. in 
the directory (first block).
