+1 on the PyXXX_ClearFreeList patch and calling them from gc.collect() as is done with the others. I agree with Guido, don't add a tp_free_list slot as the common case would be NULL. Regarding gc clearing freelists: I agree with Antoine and Martin. Clearing free lists in the highest generation of GC is a very good thing. Rebuilding them infrequently should not have a significant performance impact and makes long running python jobs better behaved by releasing more memory when possible.
