Changes between 1.5.1 and 1.6.0:
* Add *teardown* optional parameter to Runner.timeit() and --teardown
option to the "perf timeit" command. Patch by **Alex Khomchenko**.
* Runner.timeit(stmt) can now be used to use the statement as the benchmark
* Port system tune command to Python 2 (use
lseek+read/write instead of pread/pwrite which aren't available on Python 2).

CPU frequencies on IBM Z.
Night gathers, and now my watch begins. It shall not end until my death.
