My description was unclear.  I meant:

(1) Pop up the help window.

(2) In that window display some other buffer.

(3) Kill that other buffer.

What Emacs now shall do with the window is unclear.  If it does delete
the window and step (3) happens some time after (1) the effect will be
strange because the user already has forgotten about (1).  If it does
not delete the window the case where my step (3) is rewritten as

(3') Switch back to the help buffer.

will not delete the window.

I solve this problem currently by checking whether the buffer in (3) is
the buffer displayed by (1).  But this doesn't solve the problem when
(2) and (3) appear as

(2") Reuse the window to display info.

(3") Quit info.

which likely should delete the window.  [Note that making the help
window weakly dedicated in step (1) will currently have (2") fail.]
