A class Collector, it spawns several threads to read from serial port.
Collector.get_data() will get all the data they have read since last
call.  Who can tell me whether my implementation correct?

class Collector(object):
    def __init__(self):
        self.data = []
        spawn_work_bees(callback=self.on_received)

    def on_received(self, a_piece_of_data):
        """This callback is executed in work bee threads!"""
        self.data.append(a_piece_of_data)

    def get_data(self):
        x = self.data
        self.data = []
        return x

I am not very sure about the get_data() method.  Will it cause data lose
if there is a thread is appending data to self.data at the same time?

Is there a more pythonic/standard recipe to collect thread data?
