In addition to cjcox advice.
You could intercept the editor and script a flag file to show that the file is being edited and then stop edits if the flag file exists. The flag method used by unix command "vipw" to prevent two "vipw" users editing the password file at the same time.
Depending on how the file is being edited you may find unix command "fuser" useful. It is however no good for editor processes which don't open the file for write (e.g. vi).

NOTES
YP/NIS, NIS+ and LDAP users should be aware that it's possible to have conflict with users configured in here with the result that an error
will occur.
You should ensure that local user's home accounts are located on local filesystems - e.g. creating a new entry in /home when it's mounted
with automount will not work and as such the user may not be created.
