How do I make this Emacs frame keep its buffer and not get resized?

Question

My Emacs frame looks like this:

+---------------------------+
|             |             |
|             |             |
|             |      B      |
|

You could use winner-mode to be able to undo the changes to be the window sizes.

You could also explicitly save and restore the window configuration in registers.
