Uh, for when you want to associate some action with either setting
up or showing a so-called "temp" buffer (which unfortunately for
the name means a help buffer, since we have now loaded such buffers
and their displays down with help-specific stuff).

For example, to have the frame be automatically fit to the buffer
contents if there is only one window, you can do this (if you have
library `autofit-frame.el'):

(add-hook 'temp-buffer-show-hook
          'fit-frame-if-one-window
          'append)
