All the computers I have dealt with use ip6-localhost for the IPv6 loopback, 
so localhost remains IPv4 only.

The C API for connecting (and listening) have changed slightly, and it is now 
expected that the program will loop through the addresses provided by name 
lookup until it successfully connects.  So if localhost maps to ipv4 and 
ipv6, there shouldn't be a problem.
