so....
"SPAM" is Pork and Ham "spam" is unsolicited email

You should probably read up a bit on Nonstop servers (nonstop.compaq.com) before saying why they will not work!
A Nonstop server is fault tolerant at the hardware and software level. It is a shared nothing parallel processing system (MPP) rather than the SMP systems you are used to. I won't describe it in detail as the HP website does a better job.
To answer the question "is there an effective way to judge which processor is correct?", the answer is no. When an error is detected in either of the two lock stepped CPUs (or any hardware or software component for that matter) the component is immediately killed. This is called Fail-Fast. This stops the error corrupting other parts of the system. Due to its unique design the Nonstop server application will keep running despite the death of hardware and software components.
For example, certain software processes run fully Nonstop e.g. the Transaction manager. The Nonstop process "state" is constantly mirrored to another processor. If the processor running the primary Nonstop process fails fast, the backup process takes over immediately in the alternate processor. This is typically sub second.
There is far more to the architecture, but you get the idea.
