Python's cyclic garbage collector is incremental. If you can provide
a specific patch to replace it with something "better", please submit
it as a separate issue to the tracker. If you can hire somebody to
implement such a thing, go right ahead. Otherwise, I think there is
little that can be done. Python gets all of its contributions from
volunteers.
