And what happens if some of those cores are corrupt? Can you initiate
a core transfer? Will there be a stalemate? Are there any trained
Stalemate Resolution Associates around? What if there's a fire in the
Stalemate Resolution Annex?

Seriously, though, how would you go about debugging a system so
massively parallel? If most of the CPU cores are special-purpose, it's
going to require a whole new method of testing. I can just imagine
configure scripts having to be taught to cope with a new form of CPU
bug (in the same way that some still test for the Pentium division
bug).
