The simpler approach and perfectly viable without mucking up what is already implemented and working:
Don't keep returns from GAI/GNI around longer than it takes to cycle through your connect() loop immediately after the GAI/GNI call.
The even simpler approach: create an AF_NAME with a sockaddr struct that contains a hostname instead of an IPvX address. Then let connect() figure out the details of caching, TTLs, protocol and address selection, etc. Such a connect() could even support a revised TCP stack which is able to retry with the other addresses at the first subsecond timeout rather than camping on each address in sequence for the typical system default of two minutes.
