Currently, the event flow is

model_net_event -event-> sched_new -event-> sched_next -> drop into network impl

If the queue is empty, then the event separating the sched_new and the sched_next functions is unnecessary. Less events is better.

Jonathan Jenkins:

Thankfully ended up being easier to implement than expected (though with a bit of magic to distinguish a combined "new msg+schedule next" event from a "schedule next" event. No problems seen from anyone, so in it goes.
