Sorry if I wasn't clear... My point to Bill was that we should be using calls that don't have TTL information
(GAI/GNI in their default forms). That we don't need to abuse connect() to achieve that. That if people use GAI/GNI(), 
then, any brokenness is system-wide brokenness in the system's resolver library and should be addressed there.
