+ to a Python object. (Github issue #3023)
+
+* The declaration of ``PyGILState_STATE`` in ``cpython.pystate`` was unusable.
+ Patch by Kirill Smelkov. (Github issue #2997)

====================
#: Decref global variables in each module on exit for garbage collection.
#: 0: None, 1+: interned objects, 2+: cdef globals, 3+: types objects
-#: Mostly for reducing noise in Valgrind, only executes at process exit
+#: Mostly for reducing noise in Valgrind as it typically executes at process exit
#: (when all memory will be reclaimed anyways).
+#: Note that directly or indirectly executed cleanup code that makes use of global
+#: variables or types may no longer be safe when enabling the respective level since
+#: there is no guaranteed order in which the (reference counted) objects will
+#: be cleaned up. The order can change due to live references and reference cycles.
