You can guarantee that there will always be exactly one item available 
in the Queue for this thread to pull out?  Or is this a heavily edited 
example, with the required "try/except Queue.Empty" handling removed for 
tender minds? :-)

(Note the "exactly one", too, since having either fewer or more will be 
a problem for the above code.)
