How do you avoid damaging the consistency of Python objects then? I think the only way to do that would be to have a reentrant lock for each object individually. Isn't that potentially a big performance issue? I think that is the main reason behind this quote from the article: > Several attempts have been made over the years and failed to do it without sacrificing single-threaded performance.
