The condition is that all the elements in the queue->send_list could fail as a
batch. I had a bug in my patches which re-queued all the failed command
immediately and semd them out again, thus spamming the log.

This behavior doesn't exist in upstream. I just thought it might make
sense to rate limit as precaution. I don't know if it is worth the code
churn.
