Scheduled Deliveries will be sent out of sequence if you have many deliveries set at the same time

This is using build 10183.

Messages that have been rolled back are redelivered out of sequence.

For example, we publish 5 messages to a Q with message body 1,2,3,4,5 respectively.
Create a transacted session and consume all 5 messages. Do not commit or rollback. Simply close the consumer and the session. This should cause an implicit rollback.
Then create a new consumer and consume the same messages. You expect the messages to be delivered in the same order, 1,2,3,4,5.
As the results show, the sequence in which the 5 messages are redelivered is quite random. The attached log file, results.txt shows the output from the test client for 3 separate runs. In each of the three runs, the redelivered messages are in some random sequence.

We are using a 0 client side buffer (<consumer-window-size>0</consumer-window-size>).
