I won't pretend I have any details worked out. But if you look at 
functional programming, a key reason why it's so well suited to 
multiprogramming is a function can be GUARANTEED that its arguments will 
not be altered asynchronously. Furthermore, you can GUARANTEE that one 
function has no timing dependencies on another function.

The more that can be guaranteed, the less places there are for bugs to 
fester.
