For example, these methods control the disposition of the log. This requires switching the sys.stdout and/or sys.stdlog object.
Similarly, these routines determine the disposition of keyboard interrupts, which normally terminate the whole process. It may be necessary to terminate master documents threads.
Finally, these routines will permits synchronisation of delayed file updates: in a 'commit/rollback' scenario, only the process frame has enough information to permit or deny updates which may depend on all threads elaborating their client documents correctly.
Other features controlled at the process level include
the use of threads, the availability of a GUI, etc.
