The main issue is:
modify (\x -> posionWithBottoms x)
That will not fail immediatly, but will cripple xmonad by causing all commands that read the state to fail, including mod-q. Your only choice is to quit xmonad wholesale.
My proposal (shared, I believe, with sjanssen) is "fail early, fail often, and force the people who commit bugs to wear imaginary dunce caps".
Another option is to deepseq the state after every command. (That bugs like this exist in the first place is IMO a serious failing of lazy languages; where's SML-with-qualified-types-and-good-syntax when you need it? *grin*) Stefan
