You still have not renamed restore_host_debug_state() and
guest_load_debug_registers(), which you agreed to previously.

You still have not renamed guest_debug(), which you also agreed to
previously. I don't see why you have a separate function for this
anyways.

You also have not addressed the case I pointed out where an IAC matches
after you've programmed it but before you've entered the guest.
