I don't think that we should make a global change for this case, AFAIK some of the core parts of the interpreter maintain their own recursion checks with different handling of windows limits. E.g;

https://github.com/python/cpython/blob/fa106a685c1f199aca5be5c2d0277a14cc9057bd/Python/marshal.c#L25-L40

We might need to end up with the same motion and do the handling by ourselves. Wdyt @pablogsal @kj?
