Sure, but the Python interpreter can't share object between threads and the article doesn't say anything about changing that.

Of course objects can be shared. That is the whole point of threads.

OK that's true, but all access to Python objects is protected by the GIL so there is no need to use atomic operations to modify the refcount. (I should have said that objects can't be shared by concurrently executing threads.)
