I've refined

1) you won't get IP addr of remote node in/after ibw_accept. I can work this 
around, just please tell me if it's really needed.

2) +1 waiting needed after ibw_accept (you get ibw_conn in callback, not 
immediately). It's a difference from socket.

3) +1 new function is necessary to avoid memcpy (if you're really interested 
in speed): see ibw_alloc_send_buf. (memory regions need to be allocated by ib 
for sending/receiving). BTW. I assume ctdb protocol is not pingpong-like, but 
you can send/recv messages independently and asynchronously (in 1-1 node 
context). Please tell me if you don't need this.
