In this exercise you rewrite your software from Experiment 7.2 to provide multiple services.

You should, in my opinion, plan on doing the first Optional Extension, even if you never quite get to 16 services. To put it another way you should write your code in such a way that it can be easily extended to handle more services.

See the note on the use of gdb in these experiments. In effect you lose a great deal of your debugging abilities once you hit that fork.
