Major Description
After the refactoring in HAMA-521 the disk-queue is still malfunctioning. It hangs after a superstep in the method where we switch from the local queue to the messaging queue.
Generally it is useful to make a sequence diagram to know what happens when.
We want to use low overhead buffered byte writing instead of sequence files and we want to write to local disk.
Currently the disk queue is doing the exact opposite.
