I used "mib2c -c mib2c.scalar.conf" to generate the source files and then "net-snmp-config --compile-subagent" on the generated files to build the subagent.

If you mean the MODE_SET_ACTION, then I'm just copying the new string to the variable that is used in MODE_GET.
Nothing else apart from this.

Is the sub-agent supposed to actually write the persistent data to the /var/net-snmp/*.conf file?

I used "kill -9 <pid>"

Here is the relevant code. All other cases are blank.

    switch (reqinfo->mode) {

    case MODE_GET:
        snmp_set_var_typed_value(requests->requestvb, ASN_OCTET_STR,
                                 (u_char *) newStr, strlen (newStr));
        break;
    case MODE_SET_RESERVE1:
        /*
         * or you could use netsnmp_check_vb_type_and_size instead
         */
        ret = netsnmp_check_vb_type(requests->requestvb, ASN_OCTET_STR);
        if (ret != SNMP_ERR_NOERROR) {
            netsnmp_set_request_error(reqinfo, requests, ret);
        }
        break;
    case MODE_SET_RESERVE2:
        /*
         * XXX malloc "undo" storage buffer
         */
        memdup ((u_char **) &newStr, (u_char *) requests->requestvb->val.string,
               strlen (requests->requestvb->val.string));

        if (newStr == NULL) {
            netsnmp_set_request_error(reqinfo, requests,
                                      SNMP_ERR_RESOURCEUNAVAILABLE);
            return SNMP_ERR_NOCREATION;
        }
        break;
    case MODE_SET_ACTION:
        /*
         * XXX: perform the value change here
         */
        strcpy(newStr, (void *)requests->requestvb->val.string);
        break;
