We can speed up pam_opie by saving one opielookup() call in this way:

	/*
 	 * Don't call the OPIE atexit() handler when our program exits,
 	 * since the module has been unloaded and we will SEGV.
 	 */
 	opiedisableaeh();
 
 	/*
	 * If the no_fake_prompts option was given, and the user
	 * doesn't have an OPIE key, just fail rather than present the
	 * user with a bogus OPIE challenge.
	 */
	/* XXX generates a const warning because of incorrect prototype */
	if (opiechallenge(&opie, (char *)user, challenge) != 0 &&
	    pam_test_option(&options, PAM_OPT_NO_FAKE_PROMPTS, NULL))
		PAM_RETURN(PAM_AUTH_ERR);

	/*
	 * It doesn't make sense to use a password that has already been
	 * typed in, since we haven't presented the challenge to the user
	 * yet, so clear the stored password.
	 */
	pam_set_item(pamh, PAM_AUTHTOK, NULL);

 	for (i = 0; i < 2; i++) {
 		snprintf(prompt, sizeof prompt, promptstr[i], challenge);
