What's this??? You, Erik, are saying that you can design a system that copes with totally unpredictable events?

Explain, please, how you'd cope with an event that ALWAYS occurs at precisely the instant at which your MCU will go metastabile? Such a moment always exists. How do you deal with it?

While you're at it, explain, please, how you can design a system wherein you can't predict when things are going to happen. If you're referring to events in a closed system, e.g. a bus, or a plane, or even a cruise ship, or, for that matter, a planet, it's reasonable to expect you, the designer, to know these things at least to the extent to which it impacts your system. After all, it's up to you, the designer, to manage such things such that you can cope with them.

If the behavior of your code is not absolutely predictable, then something is wrong in the code. Surely you won't admit to that!
