When PYTHONASYNCIODEBUG is set to 1, this causes a strange error:

TypeError: send() takes 2 positional arguments but 7 were given

Invoke as follows:

This is an example of what seems to be a garbage collection bug in Python 3.4.0
that does not exist in Python 3.3.3.

The example uses asyncio to create a producer that multiplexes to N consumers.
On my Mac, with N=100, 38 consumers are incorrectly garbage collected and only execute
once, dropping the surviving consumer count to 62.
