Stages of Computation

Program process stages are suggested by the root of the program call graph, Figure 9.1, with computation beginning with the construction of singletons in main() via static member functions and followed by a member function call of the Shim singletree; for the common case, a run loop that waits for input and processes events; and either, given normal termination, close of the upstream connections prior to successful program exit, or otherwise, exit with abnormal return code.
