I somewhat solved the thing that way:
- by never passing to curl_multi_add_handle() an easy handle that has
not been initialized (with URL and other options);
- by doing the remove_handle() after each transfer and re-doing the
add_handle() to begin a new transfer (reusing the same easy handle);
Then I suppose reusing an easy handle with multi interfare involves
removing it after transfer has finished and adding it again to begin a
