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').

Looks to be fixed in python 3.6

Should also be fixed in the next 3.4/3.5 releases. We rewrote the guts of the Queue class to be much simpler. See https://github.com/python/asyncio (specifically, https://github.com/python/asyncio/commit/872597ba12953849cc6893042fd044073b87f870 ).
