[issue28963] Use-after-free in _asynciomodule.c

[STINNER Victor]

STINNER Victor added the comment:

I see three options:

* avoid PyObject_RichCompareBool() which can run arbitrary Python code: this can be complicated since callbacks can be proxies, functools.partial, lambda, and other funny callable objects
* reimplement the same algorithm than the Python implementation: create a new list.
* do nothing: if you do weird things, it's your fault :-)

My favorite option is to work on a new list.
