Re: Should (buffer-list) ever return killed buffers?

I strongly doubt that.  For me the reason is that `buffer-list' runs
FOR_EACH_TAIL_INTERNAL with third argument true which may quit.  The
earlier mentioned "And how running from a timer could be involved?"
should explain what happens then.

We should fix `buffer-list' appropriately.  IIUC it's broken anyway with
a non-nil FRAME argument - it nowhere checks whether the buffers on
FRAME's buffer list and buried buffer list are live.
