Function protect_jit_memory 

pub fn protect_jit_memory(access: ProtectJitAccess)

Protects access of memory mapped with MAP_JIT flag for the current thread.

Note

This feature is only available on Apple hardware (AArch64) at the moment and and uses a non-portable pthread_jit_write_protect_np() call when available.

This function must be called before and after a memory mapped with MAP_JIT flag is modified.
