When you say libcurl loops infinitely, are you aware that by default it
will wait forever for a reply and are you saying that something is
happening different from that behavior? I watched that video and I don't
see anything unusual. It looks as though you have called
curl_easy_perform and libcurl is waiting for a reply from
api.kraken.com. There is nothing unusual about that unless it's eating
CPU rather than waiting the 1 second between polls when nothing is
available to read. Enable verbose mode [1], or try the debug function
[2], or look into timeout options [3].
