Ah, very good point. I didn't think of the DNS cache.

It caches the entries in there for 60 seconds by default (and as long as the
entry is "in use") and during that period it will use the same address
order... Of course, as long as it re-uses the same connection it will also
remain using that same address (as then it won't even check its IP address

I guess this calls for a shuffle function to use when using cached results.

Anyone up for making a patch?
