Multiple addresses don't mean multiple : hosts. There is alias. In the first place, usually, both AAAA RR and : A RR point to same host. I mispoke when I said multiple "hosts" I should have said "multiple addresses." rsh used to do one address many times. It was changed to do the multiple addresses for one hostname many times and I think that's where the delay bug crept into the source, but looking at the source now it appears to have changed quite a bit from what I recall, so I'm no longer so sure.
