When I tried using this patch without a specified address, the wiimote node failed to get any data, and then gave this error on exit:

^CPipe read error (rw pipe)
Read error (cal)
Traceback (most recent call last):

I have seen this error a few times myself, but I never looked deeper into it. In my experience it happens only once at start-up and very rare. If the node is re-spawned it does not happen again. Therefore my guess is that it is a buffer overrun somewhere deeper in the system. Although I would like to find and correct this bug, it currently has low priority. If it gives you major problems, let me know and I will try to find the time...
