 // The following #defines are for using older (and less accurate) benchmark

 // timings.  They use multiple threads to get the operations simultaneous

 // but this is inherrently inaccurate (it depends whether one of them starts

 // and/or ends before the other how accurate the timings are).  If you leave

 // them both commented out then the tests will be done in a single thread

 // using asynchronous file operations, thus avoiding the problem.

 // Uncomment the following if you want to test asynchronous file operations

 // using two threads rather than in a single thread.

 // #define TEST_ASYNC_IN_THREAD

 // Uncomment the following if you want to test using synchronous file

 // operations, using two threads to do both at once.
