kauth_cred_geteuid reports surprising result


I have a user process that runs as uid root. It calls seteuid/setegid
to temporarily drop privileges. geteuid and geteuid report the 
correct euid and egid.

But in the kernel, on a system call, kauth_cred_geteuid(l->l_cred) 
and kauth_cred_getegid(l->l_cred) still give me 0 for euid and egid.

I assume I am missing sothing obvious for anyone knowledgable. Is it
obvious for anyone?
