- The interrupt-level event handlers will never enqueue an event on a
- frame which is not in Vframe_list, and once an event is dequeued,
- internal_last_event_frame or the event itself points to the frame.
- So that's all fine.
-
- But while the event is sitting in the queue, it's completely
- unprotected. Suppose the user types one command which will run for
- a while and then delete a frame, and then types another event at
- the frame that will be deleted, before the command gets around to
- it. Suppose there are no references to this frame elsewhere in
- Emacs, and a GC occurs before the second event is dequeued. Now we
- have an event referring to a freed frame, which will crash Emacs
- when it is dequeued.
-
- Similar things happen when an event on a scroll bar is enqueued; the
- window may be deleted while the event is in the queue.
-
- So, we use this vector to protect the Lisp_Objects in the event
- queue. That way, they'll be dequeued as dead frames or windows,
- but still valid Lisp objects.
