the default notification center.
Yes, observers receive notifications via the posting thread.
Also, what happens if I enqueue a notification to a thread's default
notification queue if the thread isn't the main thread? Will it be
delivered to observers in that thread, or in the main thread?
I do not know, but I would imagine that if it really is the "thread's
notification queue" the notification will ultimately be delivered by
that thread itself. (I find the alternative ridiculous, a notification
reaches the top of some thread queue so, it then signals and waits for
the posting thread to come and deliver? No way.)
