I could live with this in logic (which probably just means that I'm not
pushing the logic very hard...) but I really hate it when EPROMs specify
zero data hold time after input changes.  It makes it quite impossible to
do simple interfaces to micros without violating the theoretical rules.
At least the RAM manufacturers don't pull this vile trick.
