Which `create_stack_guard_pages` are you referring to, in `StackOverflow` or `os`?

`StackOverflow::create_stack_guard_pages` invokes `os::create_stack_guard_pages` for some preparation work (optional for some platforms) and `os::guard_memory` for protection setup.

`os::commit_memory` is not directly related to memory protection.
