Exactly. Because they are different threads - the very essence of them
is each of them having their own stacks.
Depending on what you do in the main-thread, you can do something like this:
class Worker(Thread):
def __init__(self):
...
self.running = False
...
self.start()
def run(self):
self.running = True
try:
... # work
finally:
self.running = False
In the main-thread, you test for each thread if it's still running.
while True:
time.sleep(.1)
for t in threads:
if not t.running:
print "Not running anymor: %r" % t
