That's normal. Historically, the manpage for 'rmdir' has contained a
note that "Mildly unpleasant consequences may result from the removal of
your own, or someone else's, working directory." That note is not
present in FSF's manpage, but the warning still applies. There's little
reason to lock a CWD against removal since it's contents could still be
removed (and would have to be before removal of the directory itself).
