Whoops, MPMC, of course. ;) And that wasn't even the only typo; I 
should know better than to post while distracted…

Oh, it's definitely industry-grade in that it is used to great 
effect within Weka. It's just much more of an example for an 
interesting algorithm than it is for "mechanical" code quality.

By the way, if anyone ends up testing/benchmarking this on 
non-TSO CPUs, I'd be curious to hear about the results. I hope I 
got the memory order semantics right, but of course you don't 
necessarily see much of that on x86. It would also be interesting 
to see how bad the lack of fairness can get in synthetic test 
cases.
