Fuzzing Cinder with fusil

[devdanzin]

I've been running the fusil fuzzing tool by @vstinner against Cinder in the branch meta/3.12, and while it finds some crashers, all of them but one are also in CPython and either fixed or expected to be fixed upstream.

To make this effort worthwhile, could you please indicate which branches and/or configurations would be the most interesting to fuzz, if any at all?

Also, if you can give any pointers as how to exercise the JIT (could it be as simple as calling functions/methods N times?), I can add it to the fuzzer so it might find JIT related issues. So far, only one has been found in CPython.
