PyPy breaks cycles randomly. I think a pretty comprehensive description of what
happens is here:

Well, we specifically decided that objects with __del__ methods that
are part of a cycle cannot be run.
The same reasoning was applied to generators, if they are in a certain state.
What makes iobase so special that its 'close' method can be run even
if it is part of a cycle?
It's a hack, an

What I want to know is, why is this limitation in place? Here are
two possibilities:
1) "The order of calling finalizers in a cycle is undefined so
it is not a solvable problem". But this would allow a single
object, with only internal cycles to be collected. Currently this
is not
Hello there.
For those familiar with the intricacies of the gcmodule.c, I would like to draw
your attention to http://bugs.python.org/issue9141.
I would like to consult with you to find out more about finalizers/gc in order
to improve the in-file documentation.
Traditionally, it has not been po
Dear colleagues:
I'd like to have your input on
http://bugs.python.org/issue9141
"Allow objects to decide if they can be collected by GC."
This generalizes the dynamic discovery of finalization state of objects, as
