I did a test in this direction.
I set data->result in multi_handle_timeout() and then in case of non-zero in
Curl_resolver_kill() I simple avoided calling the Curl_thread_join().
--------------------------------------------
...
/* wait for the thread to resolve the name if no error already occurred */
if (data->result == CURLE_OK) {
if (Curl_thread_join(&td->thread_hnd))
{
if (entry)
result = getaddrinfo_complete(data);
}
...
--------------------------------------------
It was just a test and it worked, but obviously it raises more doubts than
those it solves... :-)
