rm/rmdir will not let you remove dot.  It is not a good idea to that
and they avoid this pitfall.  But if you are root, and you bypass their
protection by using the link/unlink system calls you can unlink the "."
entries and link directories as well.  This can make an unholy mess
out of your filesystem.
