I was under the impression that find(1) didn't follow symbolic links?
Thus, one wouldn't ``find'' /etc/passwd if there was a link to /etc
from somewhere in /tmp.

The exposure comes from a race condition between when find has
decended into a real directory (expected behavior) and when the
'rm' is forked (expected behavior).  If between these two tasks a
real directory is replaced with a symlink (unexepected behavior)
you are going to have problems.
