As long as A has *Backtrace* as its current-buffer, get-buffer will
return it.

What significance is here to the fact that the command finishes?

Anyway, if the buffer in question is killed, but is needed elsewhere
in Emacs, then that's a bug that needs to be fixed.  We don't need to
come up with a design that works regardless of bugs, do we?
