[issue33955] Implement PyOS_CheckStack on macOS using pthread_get_stack*_np

[Ronald Oussoren]

Have you looked at benchmark results for this patch?

In particular, PyOS_CheckStack is called quite often and I wonder how those calls affect performance. If there is a clear performance impact it would be useful to store some information in the python thread state.

In what versions of macOS are there problems with pthread_get_stacksize_np() on the main thread?
