I thought it will call multi_timer_cb when called curl_multi_add_handle
immediately like below:

  rc = curl_multi_add_handle
<https://curl.haxx.se/libcurl/c/curl_multi_add_handle.html>(g->multi,
conn->easy);
  mcode_or_die(*"new_conn: curl_multi_add_handle"*, rc);

  */* note that the add_handle() will set a time-out to trigger very soon so
     that the necessary socket_action() call will be called by this app */ *

so socket_action() will wait for exiting event loop in a blocking way?
