--- Attempt to assign events sent so far a globally-unique sequence number,
--- maintaining an approximation of the order they were sent in. This can
--- introduce small ordering anomalies (where the resulting sequence differs
--- from the order they were sent in) for events that were sent close in time;
--- I've gone with chronological order here as it's the closest thing we have to
--- a global ordering, and because the results will be intuitive to most users.
