Probably not necessary, but for the record, I will correct myself. What I
meant to say here was "making them unique across the whole farm".
Obviously the message ids are already unique per-server ...

Perhaps also not necessary to say, but nevertheless: localhost_number only
affects the assignment of the message id. A server doesn't just look for
message ids containing its own localhost_number; any message in the queue
is fair game, whatever the message id.
