I don't think the underlying connect() routine will do it for you, but

that works on the good IP. With clients that know how to to this,
round-robin DNS is a cheap and moderately good failover mechanism as
well as providing load balancing among the sites that are working.
Understood - it will require a little bit of patching to implement this
- and it kinda defeats the point.
Seems like with yum's mirrorlist and metalinks functionality you just
list the individual sites that you have listed in your dns records and
it'll just work, the same.
So you have to maintain 2 things in sync instead of just one, and since
every host behind a cache is likely to choose a different mirror name
you end up downloading 10 copies of every update - or however many
mirrors there are.
