The following is the debug output of an ftp-download using curl-multi

When running same in a thread (non-multi) the switch to passive mode
works fine.
So I probably got the timing wrong.
I find this piece of code from the curl-multi-single example hard to
understand:

     curl_multi_timeout(multi_handle, &curl_timeo);
     if(curl_timeo >= 0) {
       timeout.tv_sec = curl_timeo / 1000;
       if(timeout.tv_sec > 1)
         timeout.tv_sec = 1;
       else
         timeout.tv_usec = (curl_timeo % 1000) * 1000;
     }
What exactly is it supposed to do and how could I tune it?
Or should I tune elsewhere?
Thanks,
]an
