I may be wrong, but I believe that the bug requires using the C API (not just pure Python code).  This is because Python-level lock objects have their own lifetime, and should never be freed while another thread is in PyThread_release_lock() with them.

Nevertheless, the example shows that using this C API "correctly" is very hard.  Most direct users of the C API could run into the same problem in theory.
