I *thought* that both proto udp and proto udp6 would create an IPv6 socket
bound to :: with IPV6_V6ONLY set to 0 (= accepting IPv4 and IPv6 packets
to any address). Only "proto udp4" should listen to 0.0.0.0.
(There's a catch to it, IIRC - *BSD will show the socket as "udp46" in
this case, while linux will still just display "udp6", even if it *does*
"46" on it)
Now, --multihome is a different issue - I accept that this isn't working
right in various scenarios, and we need to fix this. But at least dual-
stacked servers with "proto udp" are expected to work.
