Yikes, that's a good example you give. I will definitely keep an eye on that. Also, I realize I was a bit glowing and flippant in extolling the virtues of my proposal. But its measure shouldn't be "can it deadlock", because all locking schemes can. Rather, it should be "is it easier to code non-deadlocking code with this?" That's a judgment call, and even I haven't made up my mind yet. But I totally agree, inventing new locking schemes is a dangerous game, and I definitely hear your advice on sticking closer to the "tried and true" approaches. Thanks for the discussion. -david
