+11.15 CURLOPT_OPENSOCKETPAIRFUNCTION is missing
+
+ When libcurl creates sockets with socketpair(), those are not "exposed" in
+ CURLOPT_OPENSOCKETFUNCTION and therefore might surprise and be unknown to
+ applications that expects and wants all sockets known beforehand. One way to
+ address this issue is to introduce a CURLOPT_OPENSOCKETPAIRFUNCTION callback.
