Last month we looked at using pipes and FIFOs to communicate between concurrently running processes. However, there are occasions when you might want to run two pieces of code concurrently without the limitations of communicating through pipes. Perhaps you have two (or more) pieces of code that need to share a set of data or are constantly updating shared data structures. Pipes and FIFOs are not well-suited to handle this kind of situation because they would require each process to keep its own copy of the data and to communicate with all other processes when that data changes. Such an arrangement would cause a great deal of problems and would be very difficult to debug.
