[xmonad] Turning emacs mini-buffer window into a strut

I'm thinking that the most flexible way of doing this would be to write
a layout modifier that declares different parts of the screen to be
dedicated to certain types of clients, while the remainder of the screen
uses any regular layout. Doing this using a modifier has the advantage
that the client doesn't have to cooperate and one could have multiple
reserved screen areas (e.g., bottom, very narrow for the minibuffer,
left for emacs speedbar, etc.) If you want to do it using struts, I can
only see three ways of doing it, and neither seems too appealing:
1. Set the strut statically, but what if you want to use the same
workspace for other stuff later on. The strut is still there.
2. The suggestion by Bruce: make the minibuffer window set
3. Same as (1) but create and tear down the strut as part of window
management whenever the minibuffer window appears/disappears.
I'm not sure how to do (3), and it may in fact be easy, but I suspect
that it would end up being more kludgy than writing the above layout
modifier, which shouldn't be hard at all.
