> Erm, if you're saying that the reader thread will be highly utilized... that's not likely the case if the writer thread in this "lock free" implementation stalls out. That does not mean that the reader thread has nothing to do. e.g. the most common case is that your reader thread will produce an output, and your writer thread sends messages to change how this output is generated - but even if there's no message, the reader thread has to keep going at a steady rate.
