Haskell is driving me nuts. I really like its expressiveness, but lately I had a problem: my short program (a log parser) which used to work with constant memory footprint (thanks to good advices regarding strict data types), started to suck up more than 100Mb again. The culprit seems to be my introduction of a unit test in the module, which steps on the toes of the optimizer. Am I just unlucky, or is any haskell programmer supposed to understand in deep details how the compiler optimizes one's code?

In the meantime, I also digged a bit in the bibliography regarding replication techniques for disconnected devices. So far, I'm looking in the direction of Harmony and Rumor.
