I think Al reads this list, but the code isn't finished or released
yet as far as I know. Basically it allows you to do things like
this:

  # mkdir -p /first /second
  # touch /first/one
  # touch /second/two
  # ls -al /first
  drwxrwxr-x   2 root     root      3072 Apr  5 12:14 .
  drwxrwxr-x   2 root     root      1024 Apr  4 12:17 ..
  -rw-rw-r--   2 root     root         0 Apr  4 12:17 one
  # mount --stack /second /first
  # ls -al /first
  drwxrwxr-x   2 root     root      3072 Apr  5 12:14 .
  drwxrwxr-x   2 root     root      1024 Apr  4 12:17 ..
  -rw-rw-r--   2 root     root         0 Apr  4 12:17 one
  -rw-rw-r--   2 root     root         0 Apr  4 12:17 two
