GalileoPro`Curl_resolver_wait_resolv(conn=0x000000010b84c208,
entry=0x0000000000000000) at asyn-ares.c:395

As you may see in backtrace in original message. Curl_resolver_wait_resolv is
called inside multi_done. Curl_resolver_wait_resolv computes timeout value and
sets it to default 1 second if it’s bigger. If small (1) timeout is set prior
to curl_multi_remove_handle, then waitperform called with 0 timeout and returns
instantly without 1 second delay.
