The Python main interpreter has an at-exit list of callables, which

involved, or is the best way merely to subclass Thread?
Is that some sort of trick-question?
class MyThread(Thread):
def run(self):
while some_condition:
do_something()
do_something_after_the_thread_ends()
The atexit stuff is for process-termination which is/may be induced by
external signals - which is the reason why these callbacks extist.
Threads don't have that, thus no need.
That depends. If a thread adds an object it creates to a nonlocal
collection, such as a class-static set, does it have to maintain a
list of all such objects, just to get the right ones destroyed on
completion? Processes destroy their garbage hassle-free; how can
threads? And don't forget Thread.run( self ) in the example, if
anyone ever wants to make use of the 'target' keyword.
