+Subject: [PATCH] nodegraph: Fix refcount sanity assertion for Python 3.11
+
+Python 3.11 created immortal objects whose initial refcount is
+999999999, larger than 0xa000000. This breaks the assertin here.
+
+Caught by https://bugs.gentoo.org/906937
+
+Fortunately I don't seem to need to do a new release with this fix
+because the wheels are built with -DNDEBUG.
