> Currently, OOB messages are added to the table, then passed up unless they're already marked as OOB_DELIVERED. This could happen if another thread removed messages from the table and passed them up before the current thread could pass the message up.
> However, this work stealing might be detrimental: if the stealing thread batched messages up and 'stole' OOB messages (and those messages blocked), then the rest of the batch would be blocked from delivery.
> This is the same though if a batch only contains regular messages...
> However, this would make things simpler as threads from the regular pool would never deliver OOB messages (but not the other way round, OOB thread could still deliver regular messages).
