Like PyTypeObject.tp_clear, this function is not always called before a module is deallocated. For example, when reference counting is enough to determine that an object is no longer used, the cyclic garbage collector is not involved and m_free is called directly.

According to the documentation of module m_clear, is it correct that xxlimited module lacks m_free? Will there be a memory leak?
when "the cyclic garbage collector is not involved and m_free is called directly.", Error_Type and Xxo_Type maybe leak?
