No and yes. No in the sense that it most certainly did solve the open 
files problem. Yes in the sense that it still consumed a huge amount of 
memory and, more important to me, left me feeling that I was certainly 
doing something conceptually wrong. That was the reason for my repost, 
since I wanted to learn the 'right' (or at least more suitable) concept.

This seems to be the 'Haskell-way' solution I was looking for. I'm still 
in the progress of digging through a lot of material I found ([1-3], 
links below for other interested readers), but I think that this will be 
very helpful in the future with similar projects as well.

I have yet to test the code you send me last time, but I will give some 
feedback of it as soon as I get the chance.

Thank you very much!
Michael
