----------------------------------------------------------------
I played around with this at the UNIX level. Looks like we're not following
POSIX here:
{code}
$ mkdir k
$ touch k/j
$ chown -R -w k
$ ls -al k
dr-xr-xr-x 2 aw aw 3 Nov 5 09:59 ./
drwx------ 11 aw aw 25 Nov 5 09:58 ../
-r--r--r-- 1 aw aw 0 Nov 5 09:59 j
$ rm k/j
rm: k/j: override protection 444 (yes/no)? yes
rm: k/j not removed: Permission denied
{code}
Looking at truss output, it fails with EACCESS.
