[section:performance Performance]
Performance of __boost_coroutine__ was measured on the platforms shown in the
following table. Performance measurements were taken using `rdtsc` and
`boost::chrono::high_resolution_clock`, with overhead corrections, on x86
platforms. In each case, cache warm-up was accounted for, and the one
running thread was pinned to a single CPU.
