Subject: local admin `chmod 400` still can write

Hi.

From cygwin shell I'm able to read and write files even though my
Windows user has no permission for it. I tried `chmod` and to deny
everything for Everyone in the Windows dialog, but it didn't help. How
is it possible?

    $ id
    uid=48466(basin) gid=545(Users) groups=545(Users),0(root),544(Administrators)
    $ touch aaa.txt
    $ chmod 400 aaa.txt
    $ ls -l aaa.txt
    -r--------+ 1 Administrators ???????? 0 Jul 30 19:23 aaa.txt
    $ echo aaa >>aaa.txt
    $ cat aaa.txt
    aaa

My id is not 0, but maybe cygwin still behaves as if I was root.
