What is the expected result of doing a `chmod u+s /path/to/dir`? I assume that, as the SGID bit ensures the group ownership is inherited, you'd expect files created in a SUID to inherit the user ownership of the directory?

$ mkdir /tmp/foo
$ sudo chown ijstokes /tmp/foo
$ sudo chmod u+s,g+w foo
$ touch /tmp/foo/bar
$ ls -l !$
-rw-r--r-- 1 levesque ps 0 Nov 13 00:27 /tmp/foo/bar
