Summary: curl hangs on few cases of socks5 connections

Initial Comment:
curl hangs on few cases of socks5 connections. I use
php with libcurl 7.15.3 and I've seen this issue with
some socks servers. I wanted to make system that
tests socks5 servers with curl, however script hanged
on some socks!

I dont know socks protocol so I can say why it is
happening but here is code to recreate:

<?
$ch = curl_init();
curl_setopt ($ch, CURLOPT_URL,"http://google.pl");
curl_setopt ($ch, CURLOPT_HEADER, 0);
curl_setopt ($ch, CURLOPT_PROXYTYPE,
CURLPROXY_SOCKS5);
curl_setopt ($ch,
CURLOPT_PROXY, "221.208.173.84:3128");
curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, 5);
curl_setopt ($ch, CURLOPT_TIMEOUT, 5);
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
echo "AAA";
$xyz = curl_exec ($ch);
echo "BBB";
?>

I dont know how log socks under 221.208.173.84:3128
will work as it works now. But for now it causes curl
to hang on curl_exec. Script will show AAA but will
NEVER show BBB. Script wont timeout ever, so it will
break every script.
