> 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.
