I have personally seen cases where sorting speed is a bottleneck.

However, there are implementations that are still quite faster than this
library (I have one that is at least 3.5 faster than std::sort), and
that fares better with small sizes.

Nevertheless, it would be interesting to have a radix sorting library
implemented in generic C++.
