Well.... Any locking of the /etc/passwd and /etc/shadow should only need to
be done while adding or deleting user.  We have custom written our adduser
and delete user programs.  We have in the past just put a passwd.lock file
and checked for it or called the standard flock function.  If you wish I can
send you a copy of the source code for our delete user.  It removes their
entry from /etc/passwd and then cleans up their home directory + mailbox
into a nice .tgz file.  We have not put file locking in this one because
only 1 or 2 people on our system have access to add and delete accounts, so
it has never been much of an issue anyways.
