[reSIProcate] Opening a port under v4 and v6 simultaneously

[Byron Campen]

I was working with repro today, and found that once a port is opened  
(on a given protocol) under ipv4, attempting to open that same port/ 
protocol under ipv6 results in a TransportException stating that the  
port is already in use. On inspection of the debug logs, however, I  
see that bind is returning an error number of 98, which strerror  
decodes to "Address already in use". Has anyone else encountered this  
problem?
