Such as overriding the opcode handlers for each opcode? I suppose I could
change what the handlers are initialized to in zend_init_opcodes_handler()
so that my new handler does the serialization and then calls the regular

Yeah, so far I'm just using a different zend_execute.c with my added code, I
was just wondering if there's a better/more formal/etc way to do it...
