It isn't suitable for exchanging bigger amounts of data between processes.

May I ask why?

Well, if you were collecting big amounts of data (like dozens of megabytes) from the child process, you would probably rather want to either: a) consume it incrementally b) store it in a more economic data structure

Of course, both can be done in Haskell. I wonder if I could change my code to abstract it away...

I remember a discussion on the Haskell list about consuming database requests. The consensus was to use some pre-fold like callbacks (proposed by Oleg?) as the most general solution for such problems. You may want to look into that. Feri.
