Humm... I would also be interested in seeing a comparison between your
implementation of the algorithm and the prototype I am currently whipping up
in assembly... Humm... Calls to a DWCAS function in a loop, in C/C++, can be
fairly expensive when compared to a tight cmpxchg8b loop in assembly, that
makes no function calls with volatile/compiler-barrier restraints
per-loop... Perhaps 2-4 instructions per-loop...
