How do you plan to consume the running sums of these data? How many
different keys do you have?
If all pure stuff fails, you can always revert to imperative techniques,
using a mutable
arrayhttp://www.haskell.org/ghc/docs/6.6.1/html/libraries/base/Data-Array-ST.htmlor
something :)

Guys,
I appreciate the contribution but I'm now more confused than ever :)
On the Co-Induction-whatever thingy: Thanks, that's certainly something interesting and I'll try to find out more about it.
But it looks like none of all the proposals offers a true solution, at least none from start to finish. The amount of data is large, but finite.
So for now, I'll just stick with my initial approach as I'm running out of time.
