You could do that with a ProxyCommand: have it connect() to all addresses
returned by DNS, use the first one to return and close the others.  Writing
such a tool would be fair simple, and I would be surprised if something
like that doesn't already exist.

Try "ConnectTimeout 1s" or similar in your config for that host.
