In case it wasn't clear, I consider the current TRANSPORT_FAMILY_ALL
a misnomer. It's not like specifying "all" will make us use both
ipv4 and ipv6 at the same time0---it just indicates our lack of
preference, i.e. "any transport protocol family would do".
I mention this because this topic starts to expose that 'lack of
preference' to the end user; I do not think we want to use "all"
as the potential value for the command line option or the
configuration variable.
Thanks.
