Since baud-rate is less than search-slow-speed, Emacs has no other
choice -- it doesn't know that you're only pretending that your terminal
is slow:

,----[ C-h v window-size-fixed RET ]
| window-size-fixed's value is nil
|
| Documentation:
| Non-nil in a buffer means windows displaying the buffer are fixed-size.
| Emacs won't change the size of any window displaying that buffer,
| unless you explicitly change the size, or Emacs has no other choice.
                                            ^^^^^^^^^^^^^^^^^^^^^^^^^
| This variable automatically becomes buffer-local when set.
