Well, I don't know what you mean. tp_dealloc should always be "safe" and
is never checked for by the GC.
By the way, tp_del isn't even documented, which reinforces my point that
it's not really for use by third-party extension types.
I think we are reaching the point where, if you want this to happen, you
should ask for opinions on python-dev, because I really don't understand
which problem you are trying to solve.
