Apple suggests pthread_jit_write_with_callback_np() and a JIT callback allow list via the com.apple.security.cs.jit-write-allowlist entitlement as the way to port a JIT to Apple silicon.

We use pthread_jit_write_protect_np() at this point. How much longer is this going to work? Maybe we want to refactor this to the callback approach?

This is just a heads-up. 😺
