Sent out review for 3 of them (time for me to head out instead of
reviewing more code), and thanks for working on this.  2/5 it's not
clear to me from my first read of the spec that you shouldn't expect to
get the most recent values from either cause in your return.  5/5 my
first thoughts were "I hate wraparound logic, I'll review this later.
Also, should we even be saving off msc/ust for an out-of-order sbc
event?  Needs more thought."

I'll try to think more about these later, but I wouldn't block on me.
