[Python-Dev] PyObject_GC_UnTrack() no longer reliable in 2.7?

It seems Jim is happy with (or has at least accepted) the behavior
change. Would you still like to see it fixed (or, rather, have the
2.6 state restored)?

I think it would be possible to have two versions of
_PyGC_REFS_UNTRACKED, one being, say, -5.
_PyGC_REFS_UNTRACKED_AND_KEEP_IT_THAT_WAY would be what you get
when you call PyObject_GC_UnTrack; the code to do automatic
tracking/untracking based on contents would use some other
new API (which would be non-public in 2.7.x).
