chroot on cygwin is NOT a security measure; it is just an emulation to
ease porting.  The API exists, and allows cygwin apps to recognize a
different root.  But the fact remains that you can spawn a non-cygwin
program, which doesn't honor the chroot, and all files outside of the
chroot area are once again accessible.  Therefore, if chroot doesn't add
security, then why should ssh, which is all about security, even try to
honor ChrootDirectory?
