Another issue that I found that may be related to this problem. At the
end on my process I remove the easy handle from the multi interface and
then, I clean it up. The problem is that the socket is not closed ! And
if I do a netstat it is already in established state. It is only closed
if I call "curl_multi_cleanup" function.
