Libutil is not intended for things like this at all -- it is for
things like login handling, pty hacking, etc. People keep throwing the
wrong sorts of things into libutil and it gets rather annoying.

I don't take a position on whether pw_dup is needed or not, but it
would certainly seem to be a libc sort of thing, not a libutil sort of
