Currently, the coordinator waits for all participants to ack the decision before returning the decision to the client.

Once a participant with a prepared transaction blocks requests with a higher transaction number rather than return PreparedTransactionInProgress (~~SERVER-38028~~), the coordinator can return to the client as soon as the commit decision is persisted (with the user's requested writeConcern, including journaling preference).

Note that if the user requested w:1 writeConcern, the decision may roll back after being reported to the client, but regardless all participants will apply the same decision.
