According to Documentation/process/submit-checklist.rst, checkstack
does not point out problems explicitly, but any one function that
uses more than 512 bytes on the stack is a candidate for change,
hence it is better to omit any stack frame sizes smaller than 512
bytes, just change min_stack to 512 by default.
