There are very few programs that actually hit stack limits. MOst cases
it's unbounded recursion, signalling an error.

Nah, you cannot create a apifor this stuff, proper error handling and
adaptation to recousrce limits is a program specfic thing.

Stop using the crappy program. We prefer to apply back pressure to
crappy programming instead of accommodating it.
