Comment # 1 on bug 1230912 from Benjamin Zeller

Could this be due to timeout settings in curl/zypp?
E.G. CURLOPT_CONNECTTIMEOUT .. but iirc the default setting in zypp should
be 60 seconds for a connect timeout.

Multicurl uses fd based waiting... so even if something fails before we start
to poll() it should be no issue because as long as the event is not read from
the fd poll() should return immediately...
