At work I once needed to write a program that as part of its workload would backup a lot of images to CD. We only had 2x writers available at the time, so I spent a lot of time creating a distributed system which could write e.g. 8-16 CD's at the same time. Of course right after write speed increased dramatically and we went up to 16/32 writers...and the distributed component became totally unnecessary. But it remained in the code for a long time just complicating things for no apparent reason (to those who later took over).
