In the interests of clarity, it is useful and important to distinguish
between threading (i.e. concurrency) and parallelism. The former
relates to the programmer's view of the world, and the latter relates
to the computer's model of execution. As nomenclature, it is not
universal, but is very common, and helps avoid conflating two quite
different things.
