That's correct. Garbage collection in Python is accomplished by
reference counting. When a gets a pointer to b, b's reference count
is incremented, and vice versa. If you read the Extending and
Embedding Tutorial you can find out more about this. It's a simple
system but it means that circular references like these do not get
collected. For the time being, it's good Python programming practice
to avoid circular references in your code.

Resistance is futile. Capacitance is efficacious.
