Thanks for your well-reflected views on a one-size-fits-all reality :-)

Aah, OpenBSD.  Now, of course, OpenBSD is always right, and the single
point of reference on how operating systems should work.

The initial topic on this thread was "can we avoid extra DNS queries that
have no value, but may cause operational issues".

What happens *afterward*, whether or not the connection fails "quickly" 
or "slowly", is really of not much interest for the question under
discussion.
