> Section 121.12 of the blueprint specification has a requirement that blueprint events
be delivered to BlueprintListener.blueprintEvent() methods.  However, the implementation of
the event dispatcher submits the callbacks for each event to an executor for processing, leading
to race conditions where events can be delivered out of order.  These events really should
be placed on a queue and all callbacks completely processed in order.
