As you can see, there is no hint of DNS problems, so the
HOST_FIND_AGAIN is very strange. After downgrading to 4.60-1, the
problem went away. I suspect this might be caused by the fix to bug
#342619. More investigation to come...

Upon closer inspection I discovered that the patch deleted one line too many:
-/* Set the default yield to failure */
-
-yield = HOST_FIND_FAILED; <-- This line is not reinstated
-
-/* If we haven't found all the addresses in the additional section, we
The missing line is present in upstream 4.61 sources. Whether this means
Philip is innocent or not is not up to me to decide. :-) But it's apparently
already fixed.
