New submission from Chris Seto:
When maxsize is set on a JoinableQueue/Queue and the queue is full (maxsize <=
len(queue)) _put is called rather than __put_internal.
__put_internal increments _unfinished_tasks but _put does not.
Whenever using maxsize in a Queue calling task_done will almost always cause a
ValueError('task_done() called too many times').
