I'm not sure why you consider the code you refer to above so ugly. In any
case, I have a question and a comment on it.
Why do you use `seq` on `globalTableRef`?
You use `addToFM` to replace entries in your table. Without additional
logic to increase strictness, I think you unnecessarily risk stack
overflow. Consider the case where `writeIOGlobal` is used many times on a
global between uses of `readIOGlobal` on that global.
The above issue raises a general question: How should strictness best be
achieved with `addToFM`?
