While an easy handle is added to a multi stack, you can not and you
must not use curl_easy_perform(3) on that handle. After having removed
the handle from the multi stack again, it is perfectly fine to use it

If the easy handle is not set to use a shared (CURLOPT_SHARE) or global
DNS cache (CURLOPT_DNS_USE_GLOBAL_CACHE), it will be made to use the

If you have CURLMOPT_TIMERFUNCTION set in the multi handle (and you
