I measured the RSS memory per thread: it's around 13.2 kB/thread. Oh, that's
way lower than what I expected.
Script:
# 10: 9636 kB => 9756 kB: +12 kB/thread
# 100: 9476 kB = 10796 kB: +13.2 kB/thread
# 1000: 9552 kB = 22776 kB: +13.2 kB/thread

self.stop_event = threading.Event()

self.stop_event.set()
