> I have been extensively testing mirroring, and I'm hardening it as an overal 
> task, improving its behavior:
> - Page Transactions on mirror target are now optional.
>   * If you had an interrupt mirror while the target destination was paging, 
> duplicate detection would be ineffective unless you used paged transactions
>   * Users can now configure the ack manager retries intervals.
>       Say you need some time to remove a consumer from a target mirror. The 
> delivering references would prevent acks from happening. You can allow bigger 
> retry intervals and number of retries by tinkiering with ack manager retry 
> parameters.
>   * The ackManager was only restarted when new acks were coming in. If you 
> stopped receiving acks on a target server and restarted that server with 
> pending acks, those acks would never be exercised. The AckManager retries are 
> now restarted as soon as the server is started.
