How does one create a Singleton Orchestration?

1.    Create a correlation type with the property "BTS.ReceivePortName;" this will ensure a single instance of an orchestration, since all the messages come from a single receive location.

2.    Create a correlation set with the correlation type created in the previous step.

3.    In the first Receive Shape (Activate = true), set the property "Initializing Correlation Sets" as the correlation set (created in the previous step) and in the Second receive shape (Activate = false), set the property "Following Correlation Sets" as the correlation type (created in the previous step).

NOTE: Any promoted property which would be the same across all the messages can also be used as the correlation type property.

What happens if there is an error in the first batch that the orchestration receive and there are more to come. Does the orchestration fail and the next batch starts a new orchestration or what happens?

What's the purpose of the delay? If you leave out a delay, why are lots of CPU cycles used...?
