/*
A note about net_resolve and lookupd:
Many IRC networks rely on round-robin DNS for load balancing, rotating the list
of IP address on each query. However, this method breaks when DNS queries are
cached. Mac OS X and Darwin handle DNS lookups through the lookupd daemon, which
caches queries in its default configuration: thus, if we always pick the first
address, we will be stuck with the same host (which might be down!) until the
TTL reaches 0 or lookupd is reset (typically, at reboot). Therefore, we need to
pick a random address from the result list, instead of always using the first.
