I don't know of many clients that work this way. Most clients simply use
the first address in the list, and round-robin results in load sharing
because different clients will get responses with a different address
first. Some clients will try additional addresses if the first connection
failed, but I believe these are relatively uncommon (Unix telnet will do
this, as will some mailers, but I suspect that most browsers will not).
