Well, there's other strange effects with operating on "." and "..". At
one point, the Hurd operating system tried to honor
rename("subdir/..","other") (similar to this discussion about
rmdir(".")), with the net result of deadlocking the filesystem and
making all subsequent syscalls fail with EIEIO ("the computer bought the
farm"). There's a reason that POSIX forbids some operations on these
names, because they are too prone to bad implementations royally
screwing up your system.
