I have not encountered this.  If it's true, then the other suggestion
(of having everyone's .login/.cshrc owned by root) won't work either.

You're correct in that there isn't a good way to prevent the ambitious
users from modifying their shell setup somehow, short of totally
locking them into a captive environment where they never see a prompt.
