 It has been developed, tested and benchmarked on Linux. Yet, any C++14 platform implementing `std::atomic` is expected to compile the unit-tests and run them without failures just as well.

 ## Design Principles
 When minimizing latency a good design is not when there is nothing left to add, but rather when there is nothing left to remove, as these queues exemplify.
