> ValueError: cannot set recursion limit to 2: the minimum recursion limit is 1 at the recursion depth 1

This message looks confusing to me. 2 > 1, isn't?

The dependency of min_limit from new_limit is not monotonic:

new_limit = 99 => min_limit = 74
new_limit = 100 => min_limit = 75
new_limit = 101 => min_limit = 51
