I think it means you're created lots of thunks of the form (f x).
Perhaps some foldl vs foldl' issue? If you're not using foldl
anywhere, look at tail recursive functions and try and make their
accumulators strict.

Hi All,
I am optimizing a program to consume less memory.
If I profile it with +RTS -hd, it reports to fill 50% of my memory with stg-ap-1-upd-info.
Does this mean anything?
Regards, Robert
