And it happens that I implemented yet another such library. It is in a
heavy use and battle tested in a commercial product, but it is not
yet released, and may have some hidden bugs. Also it doesn't work on
Windows (it uses fork, pipes and AF_UNIX sockets).

The main idea behind the library is to play the same role for Lwt, as
Async_parallel plays for Async. Forking with lwt (or any other async
framework) is not an easy stuff, but it is doable. The second goal I
pursued is to make its interface as simple as possible. Task can be
created as easy, as «Parallel.run (print_endline "Hello, world")».

I hope I will release it at the beginning of the next year.
