Why is the AsyncLoop not `.daemon = True` ?

asyncloop/asyncloop/thread.py

Line 9 in 228a7e9

class AsyncLoop(threading.Thread):

If the thread is daemon you would need not to stop manually on Python exit.

Is there something bad on changing to .daemon = True or should a PR land here?

The reason is simply because I haven't been aware of the daemon feature of threading.Thread. :>

I figured out that this daemonizing feature nicely destroyed the AsyncLoop thread as you said, coding in this way:

class AsyncLoop(threading.Thread):
    def __init__(self, maxsize=100):
        super().__init__(daemon=True)

I welcome your PR! And thank you for the first issue.
