It's too bad Perl6's interesting approaches to concurrency aren't mentioned here. Supporting concurrency and parallelism were key points in the design of Perl6, and in the multi-paradigmatic way of Perl, it provides a variety of tools.

Jonathan Worthington can write and speak about this topic far better than I can so I refer you to his talk and slides:

But these explicitly don't mention the two best approaches he chose to ignore and even kill.

First the parrot threading model, which provided lockless safe threadpools, and second the pony threading model which provides the same on top of supporting shared refs, and forbids blocking IO. Which makes it even faster.

His talk ends with his simple approach taken being the best. Which is not only wrong but also a lie, because he was part in killing off the parrot threading model.

Reini, get off your crazy horse man! No one in the world, including the author of the Parrot threading model, thinks it is the "best" threading model.
