We're not talking about the same thing.  The scenario you presented --
removing the entire directory tree including the shell process's current
directory -- is not all that uncommon.  The unlikely scenario I refer to
is somehow -- I'm not sure how -- removing a directory's parent without
removing the directory itself first, which is what the OP's first message
implied he managed to do.  I don't see that scenario ever happening.  It's
unlikely.
