Exceptions are a necessary part of the C++ language, but for most programmers they are worse than worthless - they are unusable. When exceptions were first added to the language back in the days before standardization, they were seen as a brilliant improvement over the hideous setjmp/longjmp facility from ANSI C.

While Lamport’s algorithm is not particularly complex, programmers who aren’t used to working on distributed computation might find it difficult to implement. To accompany the explanation of the algorithm, I have included a C++ program designed for experimentation with the solution.
