Looks quite promising:

This is one component with two listening sockets.
The main work isn't done yet: the mca_oob_tcp_peer_start_connect.
I've extended it a little bit:
static int mca_oob_tcp_peer_start_connect(mca_oob_tcp_peer_t* peer,
uint16_t af_family);
where af_family is one of {AF_INET, AF_INET6}. I start with AF_INET
and within mca_oob_tcp_peer_start_connect, I call this function
again with AF_INET6 (one level of recursion) to try the other
address family.
This approach (coded last week when I still had a single component)
is bad (long timeouts before trying AF_INET6) and probably wrong:
for the accepting sockets, I've added
opal_event_t tcp6_send_event;
opal_event_t tcp6_recv_event;
and perhaps something like this is necessary for peers, too (don't
know this, yet. I'll have a look at it tomorrow).
So long
