Python multithreaded put () queue

Question

I am doing something very simple using multiprocessing:

data = {'a': 1}
queue.put(data, True)
data.clear()

When I use a queue on another process (using a method get()), I get an empty dictionary. If I delete data.clear(), I will get the keys as expected. Is there any way to wait for the put()serialization to complete ?
