Let's do it the same way that we lock the mailboxes then ?
If I remember right, it consists in:
1) Create a dummy file in the same directory
2) Hardlink it to the local file (/etc/passwd.lock and /etc/group.lock, possibly /etc/shadow.lock)
3) Change your stuff...
4) Unlink the tmpfile and the dummy file.
And the only other known program to change the passwords is adduser, right ?
So enabling passwd and al locking should be straightforward...
About reading, if one reads a corrupted entry while the file is changing, this shouldn't cause too much hassle (bad login)...
