Oh, good, I didn't know that.

Right. I think pure data parallelism as done with MPI isn't very
practical for an interpreter, as lots of commands typed interactively
aren't meant to be executed in parallel. On the other hand, spawning
other processes for a single parallel operation may not be practical
either. Perhaps something like a thread-pool pattern would work, where
processes are spawned upfront, but are kept in stand-by mode until a
parallel region is entered where data (and computation) is allocated to
