How does this event work? Nothing ever adds a listener to it, and it doesn't
seem to be dispatched ever.

Done.

[hshi1, 2013/01/26 02:02:17]

See the CL description -- the event is currently a TODO item, I'm leaving this
to a separate CL.

[Matt Perry, 2013/01/26 02:05:03]

I would leave this whole file out of this CL then, since it doesn't seem to be
needed until you hook up the event. Not a big deal though.
