What do you call the GC interface?  The way the GC internally
interacts with the rest of the RPython program?  Or the API exposed by
rpython.rlib.rgc?  Or are you asking from the point of view of a PyPy
user, how we will change the following sentence on
http://pypy.readthedocs.org/en/latest/cpython_differences.html?

"""Note that if you have a long chain of objects, each with a
reference to the next one, and each with a __del__, PyPy’s GC will
perform badly."""


A bientôt,

Armin.
