The problem was is currently you cna make a process, then do:
listener = lldb.SBListener("my_listener")
process.broadcaster.AddListener(listener,
lldb.SBProcess.eBroadcastBitStateChanged)
and nothing marks this as a Shadow listener, so when we go to deliver events,
we don't wait on the consumption by the Primary listener.
But I don't think I should need SetShadow for this. I don't think we need to
mark the listener outside the "Add" action as Shadow. Instead, AddListener
should see if there IS a primary listener, and if there is one, then any other
listener has to be a shadow listener.
Actually, I wonder if we really need this distinction to be marked explicitly,
I might have been being too general. If you have a primary listener, then all
the other listeners have to be shadow listeners. I don't think anything else
makes sense. And conversely, if you don't have a primary listener, then I
marking some of the listeners as shadow doesn't do anything useful.
