Aren't we heading for the same problem the way things are going with dynamic frequency scaling in AMD and Intel processors? How do you predict when a particular workload running a little hotter than anticipated will make it kick in? If the answer is to benchmark them at the factory under carefully controlled conditions and reject those that don't fall within a narrow range, then what's the difference?

It's similar. The difference is that there are way more dimensions in asynchronous processors.

Anyway, when I was studying the subject, the one problem people wrote about was testing. I think the GP's problem and the one I pointed can only get some attention after tests get reasonably solved, and they both may be easier than they look like.
