A flexible, lightweight, spin-lock barrier

Do you really need a total ordering of messages instead of the partial ordering that separate queues could give you? Also do you really need broadcasting or point-to-point or anycasting would be more appropriate? That's what I mean by specialized.

If the consequences of any given event may impact the processing of any subsequent event, then yes. For many ordinary systems this constraint holds true.

But partial ordering is often sufficient to maintain causality, total ordering might be overkill.
