[concurrency-interest] AtomicReferenceweakCompareAndSet "Mayfailspuriously"?

So, as you turn the crank some display would say something like:

   Read of this.field, possible values: 5, 25, 17.

This would be a real challenge to write.  Not just making it figure out
all the possibilities from multiple threads, but also coming up with a
clear an usable display.  And a properly written program would make *no*
use of the hardest part of the work!

I'm ready for the visible VM. Just turn the crank very, very slowly and 
all will be revealed. So in this case the surprising/not 
apparent/spurious/data race order is "read null, write int[], read 
int[], write int[]{1}".
