My best guess would be that something is raising on 3.13, and then the C code that has a failure path makes a `Py_DECREF` to a reference it doesn't own....

Ok, thanks. I'll post to the thread to see what we can do. In the meantime, I'll keep this open in case we need to do anything upstream e.g. to...

Confirmed it on Linux, for both 3.12 and main. FWIW, the script does print out `end` for me, but it hangs upon interpreter finalization, so it doesn't really show up...

I do think this is possibly a security issue. It looks like this applies to any iterable greater than 65514, so if user input was passed to `Queue.put`, this is...

Upon further investigation, this looks unrelated to `multiprocessing` and is just a nasty side-effect of `os.pipe`. Apparently, writable files returned by `pipe()` have an internal limit of 65536 (i.e., the...

Definitely getting closer to fruition. The main part that I need to iron out is the partial matching. It's not yet clear to me how to execute the `except*` block,...

Probably a duplicate of either #3457 or #3469. I'll get to this soon.
