Pending in memcached_quit!!

example code:

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <time.h>
#include <unistd.h>
#include "libmemcached/memcached.h"

int main()

        servers = memcached_server_list_append(NULL, (char*)"127.0.0.1", 11211, &rc);
        // servers = memcached_server_list_append(servers, (char*)"localhost", 30000, &rc);

        rc = memcached_server_push(memc, servers);
        memcached_server_free(servers);

        const char *keys[1]={ NULL };

        memcached_result_st result;
        if (!memcached_fetch_result(memc,
                                &result, &status)) {
                printf("%d\n",status);
