:     You must stop each thread from inside the thread.  So have some flag
: somewhere that it can check to see if it needs to shut down early.

Actually, you only need to stop non-daemonic threads.  For example, if all
the threads (but the main thread) are daemonic, then calling sys.exit in
the main thread will exit the program.  (To make a thread t daemonic,
execute t.setDaemonic(1) before starting the thread.)

Finally, if you *must* rudely exit the program from a non-main thread, you
can use os._exit.  You're supposed to avoid this, but ...
